For this investigation, they need to compile their own reports. As this year progresses, learners will have to start filling in more parts of the concept maps themselves, and then hopefully draw their own ones by the end of the year. High initial rates of gas-exchange in respiration and photosynthesis of Chlorella. Their interaction extends to photorespiration, which is linked to optimize photosynthesis. The gas that they collected from each test tube was run through limewater. For example, read the concept map as follows, "Respiration takes place in all organisms. Browse . When this fuel is burned in the presence of oxygen, the chemical potential energy is transferred into light and heat energy. For example, both processes synthesize and use ATP, the energy currency. 5. Pharmacies are generally quite helpful and will assist schools in purchasing low cost syringes. Abstract. [1 mark], Why do you think the yeast solution in Set-up 1 did not produce carbon dioxide. Real understanding and knowledge comes from grappling with the subject matter, and not just memorizing facts. ATP is not energy itself, but instead it stores energy. First decide what question you are trying to answer and the aim of your investigation. Consumers require the products of producers (e.g. Chloroplasts are only present in plants. We will place some pot plants in the light for a day, and some other pot plants in a dark cupboard for a day, and then perform the investigation on the leaves of plants from both groups. It also produces water and carbon dioxide as by-products. •Plants such as grass use energy from the sun to make its own food, therefore its called an Autotroph. Similarities between Photosynthesis and Cellular Respiration, Differences between Photosynthesis and Cellular Respiration. A very small percentage of atmospheric air is carbon dioxide gas (0.03). Sugar and oxygen O2 are produced in photosynthesis. All living organisms need to undergo respiration to release energy from chemical potential energy and perform the seven life processes. In photosynthesis, what form of energy is sunlight converted to, and how is this energy stored? Others like to make things even more visual, using pictures and diagrams to form their summaries. They have also been introduced to photosynthesis in the context of green plants and food chains in Gr. What does this mean? Photosynthesis Respiration Basis Of Comparison Location Starting Raw Materials End Products Energy Requirement 1. of energy like heat and motion (energy required for cellular processes to occur.) Together, these two processes form a cycle that helps maintain constant levels of oxygen and carbon dioxide in the Earth's atmosphere. [2 marks], Study the following diagram and fill in the missing information. The chlorophyll must be removed by first dipping the leaf into boiling water for 1-2 minutes to remove the waxy top layer. An idea as introduction and/or conclusion to this section on Respiration is to let learners watch the YouTube video of a song about cell respiration: bit.ly/1eupZUz. This is a map of how all the concepts (ideas and topics) in this chapter fit together and are linked to each other. When the sugar was not available it could not react and could not produce carbon dioxide. 10.3. The oxygen produced by plants during photosynthesis is what humans and animals inhale for the blood to transport to the cells for respiration. Hypothesis: The green parts of variegated leaves will turn blue-black in iodine solution indicating that they photosynthesise and store starch, whereas the white parts will not turn blue-black (will stay brown). The glucose is then turned back into carbon dioxide, which is used in photosynthesis. This food contains chemical potential energy that needs to be released from the food. It is important that learners be made aware that we do not taste-test unknown substances due to the potential for poisoning. Activity: Does our breath contain carbon dioxide? [2 marks], Explain why you predicted this outcome for his beans. We want to find out which parts of these leaves photosynthesise in this part of the investigation. For example, a reptile can lie in the Sun to warm up from the heat energy, but this does not provide the necessary energy for that animal to move, reproduce or excrete waste. They have been classified according to topics and also provide tips on how to incorporate the articles into your classroom. 9 when they do body systems and also cover the circulatory and respiratory systems in detail. Created by. They can then indicate the results on the drawings. Photosynthetic Reaction. As air contains such a small percentage of carbon dioxide, there is not enough to cause a noticeable difference in the limewater. They can also do this in groups. As the bananas ripen, the starch is converted into glucose. Finally, what does photosynthesis release as a by-product? B. The hot water removes the waxy cuticle and the alcohol dissolves the chlorophyll, releasing the green colour of the leaf. In this investigation we will taste the bananas to determine if they have more glucose or more starch. Test. You then need to think back to part 1 and design the method for your investigation. While photosynthesis is performed by most plants which can prepare their own food, most animals fulfill their energy requirements throug… Now that we have looked at how green plants produce their own food, let's find out how all living things release the energy stored in food in order to perform the life processes. Water and carbon dioxide are by- products and ATP is energy … What is potential energy? Start studying Photosynthesis and Respiration. Place a few tablespoons of calcium hydroxide, Ca(OH), Leave the suspension to settle for a few days. You can also take a walk around your school property and surrounds to see if you can find any variegated leaves. A really good demonstration of the various experiments in this and subsequent sections is found at . Record your observations in the table. Assessment Rubric 4 can be used to mark this table if you would like a more in depth assessment. It is not crucial to do this investigation if you do not have time. [2 marks], Describe the test that the farmer conducted to show that the leaf contained starch. Quiz not found! cellular respiration. Next term in Matter and Materials, we will look at chemical reactions and define the 'ingredients' as reactants. [6 marks], Draw a table in the following space to show the differences between the two processes, photosynthesis and respiration. Unlike photosynthesis, where we place sunlight energy above the arrow and not as one of the reactants in the equation, in respiration, we place energy here as a product. What is the end product of photosynthesis and respiration? Fill in the products of respiration in the block on the left. This is what learners' diagrams should look like: Have you noticed the VISIT boxes in the margins which contain links? answer choices . An example of a possible answer is: To investigate the presence of starch in ripe and unripe bananas; To investigate why bananas becomes sweeter as they ripen; etc. We will learn more about chemical reactions next term in Matter and Materials. Write. 4. This is the metabolic process in all organisms where oxygen is combined with glucose to release water and carbon dioxide and energy in the form of ATP (adenosine triphosphate). This means our breath contains carbon dioxide from respiration. Carbon dioxide is released as a waste product back into the atmosphere C6H12O6 + 6O2 → 6CO2 + 6H2O. (Take not that learners have not yet started to call the starting ingredients reactants), Table of differences between photosynthesis and respiration, Starting ingredients/requirements (reactants), Carbon dioxide, sunlight energy and water, Organisms in which this process takes place, During the daytime/when there is sunlight, All the time as organisms continuously respire. Some of the energy is used to make ATP in the mitochondria during cellular respiration, and some is lost to the environment as heat. Figuring out the study method that works best for you, and developing these skills is very useful, especially for later in high school and after school! Therefore the plant converts glucose into starch, which is insoluble in water. Remember, food is the fuel for our bodies. Think of an unripe green banana and a ripe yellow banana. The Sun provides energy to the Earth in the form of radiant (light) energy and heat energy. Discuss this with your learners. Make a hypothesis for your investigation. This was done to allow some plants to photosynthesise and the others not. (Solar energy), "What do plants get from the soil that they use for photosynthesis?" Respiration uses oxygen while carbon dioxide and water are given off as by-products. Hence in photosynthesis you have the light dependent reactions and the dark reactions while in respiration there is aerobic respiration and anaerobic respiration. Simply type the link exactly as it is into the address bar in your browser. All living things require energy to survive. 5. They are also called a producer •A caterpillar obtains energy from eating the grass and a bird obtains energy by feeding on the caterpillar. Neither matter nor energy can be created or destroyed, and both move through systems. Learners may get confused and think that because photosynthesis occurs during the day, that respiration only occurs during the night. Learners need to learn how to learn! You also need to fill in the three things that plants use to photosynthesise. Plants that lose their leaves in winter store food produced during the summer by photosynthesis. The seven life processes are: movement (moving), reproduction (reproducing), sense the environment (sensing), growth (growing), respiration, excretion (excreting), nutrition (feeding). Why do you think you observed the result you did when you pushed air from the atmosphere through the limewater? The plant cannot have large amounts of glucose accumulating as this affects the water potential within the leaves, and so some is converted to starch to be stored until it is needed. An alternative to a large syringe is to use a bicycle pump or balloon blower. The ivy has a very thick cuticle and the iodine can't penetrate the leaf easily. Aside from using light energy, photosynthesis includes carbon the oxide and water. Heat the saucepan over the bunsen burner or the stove. Photosynthesis and cellular respiration are the life processes performed by most living organisms to obtain usable energy from nature. Photosynthesis And Cellular Respiration Flashcards Preview ... What is the energy required for photosynthesis? Materials and apparatus: This should be a similar list to what was used in Part 1. Q. Which test tube do you think it is and from which set-up. The plant converts the glucose to starch as it is easier to store. Glucose is used as food by the plant and oxygen is a by-product. Do you remember what the seven life processes are? ...Photosynthesis and Respiration Unit2 – IP 1. You need to look at what concepts link from these in order to know where to put each one. A Gr. The steps in the method must be numbered. If the limewater changed from clear to cloudy white then this would indicate the presence of carbon dioxide. It is a colourless gas, so we cannot see it directly. This provides them with energy. 2. Fill in the requirements of photosynthesis in the block on the left and fill in what type of energy is needed and the name of the pigment that absorbs the energy. and water - using light energy. In humans, we do this by breathing out carbon dioxide-rich air. Part 2 : Which parts of variegated leaves photosynthesise? This concept is developed within the scope of the CAPS prescriptions and will be used as a scaffold to explain the transfer of energy in the ecosystem in the subsequent chapter. Let's find out. Produces energy in cells - cellular respiration, The REACTANTS of cellular respiration - glucose and oxygen, The PRODUCTS of cellular respiration - carbon dioxide, water and ATP, In which organelle does cellular respiration occur? Explain what you think happens to the starch as the bananas ripen. Those that did not receive radiant energy did not photosynthesise so they tested negative for starch presence (iodine solution remained yellow-brown). In photosynthesis the ingredients/ requirement for it to place is water and carbon dioxide as they release oxygen and glucose as the products. Photosynthesis During photosynthesis light energy from the sun causes carbon dioxide and water to be transformed into glucose (sugar) and oxygen. This energy is then used to drive all the other processes in your body. For example in this case you could read: "Respiration takes place in all organisms, releases energy from food". Our most important source of energy is the Sun. You will also learn more about respiration in later grades. The emphasis in this chapter is on the use of energy and on how radiant (light) energy is transferred to chemical potential energy and later released during respiration. What Is Fermentation? Describe what you observed when you used the syringe to bubble air from the atmosphere through clear limewater. The following photo shows one of the test tubes after the experiment. While photosynthesis is performed by most plants which can prepare their own food, most animals fulfill their energy requirements through cellular respiration. Photosynthesis is the process whereby green plants use carbon dioxide from the air, water from the soil and radiant energy from the Sun in a series of chemical reactions to produce glucose (food) and oxygen. Photosynthesis:respiration (P:R) ratios were significantly and negatively related with temperature between 18 ~ and 31~ for all Hawaiian cor- als, whereas at Enewetak this ratio generally showed a curvilinear relationship for this temperature range. In this section, we will be looking specifically at cellular respiration as we will be looking at the chemical reactions which release the energy in food. Record some of your discussion points. Glucose is soluble in water. Some objects with potential energy are a book on the table (it has gravitational potential energy as it can fall down to the ground), a bouncing ball when it is at the top of its bounce as it can also fall back down, a batteries, fossil fuels have and food have potential energy. The second method which has been employed is the measurement of oxygen uptake of illuminated cells deprived of C02 (inhibition of photosynthesis) (3). Up until now learners have been provided with a framework in which to write up their results. Photosynthesis and Respiration 3 Model 2 – The Carbon Cycle Green D Atmospheric CO2 D C B Auto and factory emissions Respiration Combustion Red (A) A Feedi Wastes ng Death Red Decay (by decomposing fungi, bacteria, and worms) on ati rm o lF ue lF ssi Fo Carbon Stores (coal, oil, natural gas) 13. Variegated leaves have white patterns (areas lacking chlorophyll) on them. Get learners to look at the leaves and discuss the investigation first. United States. The clear limewater did not change and remained clear. You will need variegated and normal leaves for this investigation. Have you ever wondered why fruit becomes sweeter as it ripens? Point out that air from your lungs contains a much higher percentage of carbon dioxide from respiration and so this is able to turn the limewater cloudy in a shorter time than atmospheric air will. Summary. ), The learners did not want to lose any of the gas that might potentially form before it had time to bubble through the limewater. There is a very well known test for detecting carbon dioxide using clear limewater. In these books, the focus question will be the main topic for the chapter. Learners must make drawings of their leaves at the start of the experiment, indicating the different coloured regions as boiling in alcohol will remove the colour. Therefore, the estimated maximum energy efficiency of photosynthesis is the energy stored per mole of oxygen evolved, 117 kcal, divided by 450—that is, 117/450, or 26 percent. Plants are able to photosynthesise because they contain chlorophyll, a green pigment that can capture light energy from the Sun. Plants also produce cellulose fibres that give plants strength and support and are important to our digestive systems as roughage. Often a concept map has a "focus question" from which the other concepts radiate. 5. answer choices . This is a good opportunity to discuss kinetic energy and temperature of a solution. have to write up their own report. The leaves in the light will test positive for starch as they photosynthesised, whereas the leaves in the dark will not photosynthesise and will test negative for starch. The bioenergetic processes of photosynthesis and respiration are mutually beneficial. A concept map gives us a more visual way of summarizing information. So how does this happen? Do you remember how we represented photosynthesis as an equation to show what goes in and what comes out? Comparison chart Photosynthesis Respiration Production of ATP Yes Yes; theoretical yield is 38 ATP molecules per glucose but actual yield is only about 30-32. Therefore, the estimated maximum energy efficiency of photosynthesis is the energy stored per mole of oxygen evolved, 117 kcal, divided by 450—that is, 117/450, or 26 percent. The radiant energy of the sun acts as a reactant because it is required by photosynthesis but is not produced by photosynthesis A. Leave the leaf in the alcohol until all the chlorophyll has been removed from the leaf and the alcohol turns green. If you do not have time to do both parts of the investigation, a suggestion is to get your learners to read through Part 1, and then to conduct Part 2 where they Cellular respiration uses glucose and oxygen to produce carbon dioxide and water. Google Classroom Facebook Twitter. 10. Record your observations in a table. We think you are located in The equation for cellular respiration is the direct opposite of photosynthesis. The chlorophyll needs to be removed from the leaf so it does not mask the colour change we expect with the iodine solution. Match. He was scared that his little brother would knock his tub over, so he hid the tub in his cupboard. B. The lower quantum requirement obtained at low light intensity is believed to be due to a relatively greater importance of contribution of energy from respiration to photosynthesis. For example, the temperature of the water will affect the rate at which it dissolves, as will the quantities used, etc. 6Co2+6H2O—>C6H12O6+6O2 Where does the energy come from in photosynthesis? Log in Sign up. Some might notice a very slight change, which indicates that there is a small amount of carbon dioxide present in atmospheric air. We know what is required for respiration to take place in all organisms. [3 marks]. Photosynthesis is an endothermic reaction. Learners need to apply what they have learnt in Part 1 to plan their own experiment in part 2 and write up an experimental report. After 4 weeks N was supplied to treatment plants as NH 4 NO 3, KNO 3, or NH 4 Cl and rates of C 2 H 2 reduction, root + nodule respiration, and leaf photosynthesis were determined 1 week later. Processes in photosynthesis are divided on basis of requirement of sunlight while respiration processes are divided on basis of requirement of oxygen. Trapper plants were inoculated and grown in a controlled environment on N-free nutrient solution. Search. In physiology, respiration refers to the transport of oxygen from the outside air to the cells and the transport of carbon dioxide out of the tissues and into the air. Why do we need to eat food? Spell. ATP is used in different ways mostly in animals for contraction, protein synthesis, and mental process. 9, and how breathing, our blood circulation system and respiration all work together as one system within our bodies. This investigation can be done over 2 lessons. ... What happens in both respiration and photosynthesis? Make sure your learners understand what a concept map is and that they have filled in the correct concepts into the empty spaces. No – energy is stored in the bonds between atoms of the glucose molecule 8 What is the energy source of photosynthesis? All organisms release energy from food, called …........." What type of energy does food contain? We call it a by-product as it is not the main product that is wanted from the process. The word and symbol equations for photosynthesis are: Be careful not to confuse this photosynthesis equation with respiration which is the reverse of this. 1 big yellow energy sign; 2. [4 marks]. Post the equations of these processes where the students can see them. Chapter 2: Interactions and interdependence within the environment, http://www.sciencenewsforkids.org/news-in-the-classroom/, http://www.flickr.com/photos/gr33n3gg/3445868159/, http://commons.wikimedia.org/wiki/File:Elysia_chlorotica_%281%29.jpg, http://www.flickr.com/photos/tessawatson/3216911479/, http://www.flickr.com/photos/crabchick/5810139262/, http://www.flickr.com/photos/yimhafiz/2517494621/, http://www.flickr.com/photos/design-dog/1249337589/, http://www.flickr.com/photos/tessawatson/379270115/. There are many examples of South African plants that have variegated leaves, such as some geraniums, African violets, ivy, etc. There are two parts to this investigation. We will also conduct a starch test on the ripe and unripe bananas to see which contain more starch. Do plants undergo photosynthesis and respiration all day and all night? Photosynthesis is the process in which chlorophyll molecules absorb the radiant energy from the sun and transfers it into chemical potential energy. a range of pot plants that can be easily moved around, 100 ml beaker or glass jar in a saucepan with water, glass petri dishes, white saucer or white tile. Share it! Photosynthesis and cellular respiration are both part of a mutually beneficial relationship. Hypothesising, investigating, observing, measuring, recording, analysing, writing, group work. (This question test the learner's ability to follow the logic of the experiment and to link the theory learnt and the practical application of it. Use the test above to test whether there is starch present in the leaves from the plants that were kept in the dark. Take a piece of the ripe banana and a piece of the unripe banana and compare the tastes and textures of each. Remember to take down some notes in the margins of your workbook as you discuss things in class. In your discussion, you need to explain your results and what they mean. This helps to remove the waxy cuticle that covers the leaf and breaks down the cell walls. For now, let's use this test to show that our breath contains carbon dioxide. Work in groups of three or four. 8. The learner's diagram should look as follows: The process of photosynthesis can be presented in the form of an equation: What happens to the glucose that plants produce during photosynthesis? BACK TO EDMODO. Ask your learners this as a revision of what they did in previous grades. All life on Earth depends on energy to sustain the seven life processes. The clear limewater turned cloudy white. A concept map provides another way of representing information (ideas and concepts) in a more visual way. Photosynthesis involves the use of energy from sunlight, water and carbon dioxide to produce glucose and oxygen. You should use this comparison to help learners understand that reliability of an experiment rests on the fact that although different people perform the same test they should all reach very similar results. It therefore needs to be heated in a water bath. Place half of the plants in the dark for at least 24-48 hours and the others in a well-lit area of the class that is exposed to lots of natural sunlight. This chapter provides learners with an introduction to, and revision of, the concepts in photosynthesis and respiration in preparation for a study of the ecosystem. Thus, the energy used is 9 × 50, or 450 kcal per mole of oxygen evolved. In contrast, cellular respiration is a catabolic process resulting in the breaking down of organic molecules to release energy. Which banana do you think contains the most starch and the least glucose (a sugar) based on the taste test? Below is the complete concept map with the answers filled in. At the to… The "Key concepts" listed above is a summary written out in full sentences. The processes of photosynthesis and cellular respiration are linked to each other. Learners should be able to quite easily see this based on the speed with which the iodine changes colour in the unripe banana. From Sunlight? Photosynthesis converts carbon dioxide and water into oxygen and glucose. Technology teachers at your school might also have syringes for their syringe mechanics lessons. a. salinity (how much salt) of the water and high temperaturesb. Variegated mint-leaf is also very good for this investigation, and is a common plant in Kwa-Zulu Natal. In this chapter we are going to investigate the processes involved in transferring the Sun's energy to our bodies to allow us to read this text! Attach a rubber tube to the front of a syringe.
