M4 L2 Gizmo Simulation: Cell Energy Cycle Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. What does a plant need to survive and grow? Water air sun 2. What does an animal need t ... o survive and grow? Water food shelter 3. How do animals and plants depend on each other? Animals eat the food and the plants grow off of it Gizmo Warm-up The Cell Energy Cycle Gizmo™ illustrates two processes that are essential to life: photosynthesis and cellular respiration. Although both of these reactions involve a series of complex steps, the basic reactants and products in each process are four relatively simple molecules. 1. What is the chemical formula of oxygen? 02 2. Glucose is a simple sugar. What is the chemical formula of glucose? c6h1206 3. What is the chemical formula of carbon dioxide? c02 4. What is the chemical formula of water? h20 Activity A: Photosynthesis Get the Gizmo ready: · If necessary, click Reset. · Check that the PHOTOSYNTHESIS tab is selected. Check that Description is turned on. Introduction: Photosynthesis occurs in the chloroplast, an organelle found in plant and algae cells. Within the chloroplast, a green pigment called chlorophyll converts the radiant energy of sunlight into chemical energy that the plant can use. Question: What are the reactants and products of photosynthesis? 1. Predict: Of the molecules shown on the CHEMICALS pane, which do you think are reactants (ingredients) in photosynthesis? Which do you think are products? A. Reactants: light energy, carbon dioxide and water B. Products: Oxygen that is released into the atmosphere. Glucose that is used by the plant as energy and to make other molecules such as starches and sucrose Explore: Drag each molecule from the CHEMICALS pane to the chloroplast on the PHOTOSYNTHESIS pane. If a molecule is a reactant, it will stay in the chloroplast. 2. Which molecules are reactants in photosynthesis? H20 c02 3. Observe: Click Add light and look at the Output. What are the products of photosynthesis? 02 c6h1206 4. Summarize: A chemical equation shows reactants on the left side of an arrow, and products on the right, like this: reactant + reactant → product + product. Based on your observations, what is the chemical equation for photosynthesis? Turn on Show chemical equation to check. Were you correct? [Show More]
