Description

Photosynthesis and Cellular Respiration Web Activities Part 1 - View the following Amoeba Sisters video on photosynthesis and answer the questions below. In 10 minutes, you will be sharing your answers with a partner. 1. What kinds of organisms can perform photosynthesis? Which types of organisms cannot? Plants are the only organisms that perform photosynthesis. All other organisms are not capable of this process. 2. How do organisms like amoebas, animals and humans benefit from photosynthesis? Amoebas, animals, and humans benefit from photosynthesis because we all eat plants and plants make their food and survive through photosynthesis. 3. What chemical allows plants and other organisms to perform photosynthesis? How does this chemical help “catch” light from the sun? Chlorophyll allows plants to perform photosynthesis and this captures red and blue light but reflects green light. 4. Are green plants the only plants that perform photosynthesis? Explain. No, because there are more pigments besides chlorophyll. 5. How are the products of photosynthesis useful to the plant itself? How are the products of photosynthesis useful to other organisms? The products provide both plants and animals with energy. 6. In a food web, what does it mean for a plant to be a producer? What does it mean for an animal to be a consumer? A plant produces its own food while an animal consumes the food that the plant produces.

Part 2 - Read the following cK-12 article about how photosynthesis and cellular respiration are related and answer the questions below. In 10 minutes, you will share your answers with a partner. 1. What is needed for photosynthesis to occur? Be specific to what are the reactants and what are the products. Carbon dioxide, water, and the sun’s energy are the reactants. Oxygen, glucose, and ATP energy are the products. 2. What is needed for cellular respiration to occur? Be specific to what are the reactants and what are the products. Oxygen, and glucose, are the reactants while carbon dioxide and water are the products. 3. What is ATP? ATP is the product of cellular respiration. 4. How are the equations for photosynthesis and cellular respiration related? The cellular respiration is the opposite of the photosynthesis equation. 5. What do the respiratory system and cellular respiration have in common? A. 1. Oxygen plays a key role in both 2. They both rely on the heart 3. They both expel oxygen as a waste product 4. They have nothing in common 1. Why was your answer correct? Because both the respiratory system and cellular respiration wouldn’t function without oxygen. 6. What are the chemical products of cellular respiration? D. a. Water and amino acids b. Carbon dioxide, nitrogen and urea c. Oxygen, lactic acid, and ammonia

d. Carbon dioxide, water and ATP i. Why was your answer correct? Because cellular respiration produces carbon dioxide, water, and ATP.

7. In which organelle does cellular respiration take place? B. a. Nuclei b. Mitochondria c. Ribosomes d. Golgi bodies i. Why was your answer correct? Because cellular respiration takes place in the mitochondria....
