Photosynthesis – From Light to Food

Pre-Assessment Write a T or F in the space provided if you think the statement is true of false. 1.Photosynthesis happens in plants and not in animals. T

2.The cell wall captures sunlight and converts it into glucose. F

3.Both plants and animals need oxygen to release energy from food. T

4.All living things must eat other living things for food. F

5.Plants can’t make their own food. F

6.Nearly all life on Earth gets energy from the Sun. T

7.Photosynthesis takes place in the roots of a plant. F

8.In photosynthesis oxygen is transformed into carbon dioxide. F

9.Plants produce glucose for other organisms to eat. F

10. A producer eats other organisms. F

Short Answer 11. Describe what happens in photosynthesis and what its purpose is. In photosynthesis, light from the Sun is changed into food by plants. The purpose of photosynthesis is for the plants to make food for themselves although other organisms eat plants, too, for fuel.

12. What is the chemical equation for photosynthesis?

6CO2 + 6H2O ==> C6H12O6 + 6O2

13. Explain how photosynthesis connects plants with animals with energy from the Sun.

Photosynthesis provides chemical energy to plants and animals using energy from the Sun. Plants make their own food directly while other organisms (consumers) eat plants as food.
