11. How do plants make their food?
Photosynthesis
A process where plants and other organisms convert sunlight energy into chemical energy that is used as food

12. Photosynthesis
Reactants (what’s needed)
*Water
*Carbon dioxide (CO²)
*Sunlight energy

13. Where does photosynthesis take place?
*In the Chloroplast (Chlorophyll – captures the sun’s energy here)

14. Photosynthesis – What does it produce?
oxygen
sunlight
*Products
water
Food
*glucose
*sugar
*carbohydrates
Carbon dioxide

15. Is all of the food produced by plants used for energy?
Yes – for the plant itself (to carry out its functions) or for other organisms to eat

16. Photosynthesis Essential Question
