Chloroplasts are the site of photosynthesis, absorbing sunlight to help produce glucose sugar (food) for the cell. Take a look at the diagram of photosynthesis below. Process of Photosynthesis Sumlight Oxygen Carbon diaxide Glucose Sugars Water (H,0) 4. What process occurs in the chloroplast? 5. Reactants are substances that go into a chemical reaction. Looking at the picture of photosynthesis above, what are the three reactants of photosynthesis? 6. Products are substances that are made or created in a chemical reaction. Looking at the picture of photosynthesis above, what are the two products of photosynthesis? 7. In a chemical equation, we write the reactants on the left side and the products on the right side with an arrow in between. Fill in the reactants and products that you fournd for photosynthesis from the previous questions. Process Chemical Equation Photosynthesis
