1

What two things happen in light independent reactions?

Carbon fixation
Carbon reduction

2

What is carbon fixation?

converting C02 into sugar

3

What is carbon reduction powered by?

ATP & NADPH from light reactions

4

What do plants do with the glucose?

Cellular respiration
Produce cellulose
Store excess as starch/sucrose

5

What are 85% of species?

6

What do C3 plants do on hot days?

Close stomata which decreases C02 and increases 02 which causes photorespiration

What are CAM plants?

succulents, cacti, pineapples

12

How does photosynthesis moderate the greenhouse effect?

by removing C02 from the atmosphere
