Question 13

What is C3 photosynthesis?

Answer 13

normal photosynthesis

Question 14

What is C4 photosynthesis?

Answer 14

Has mesophyll and bundle sheath cells. CO2 is stored in the mesophyll cells as C4 and when the stomata closes at the hottest part of the day, it converts C4 back into CO2 and releases it to the bundle sheath

Question 15

What is CAM photosynthesis?

Answer 15

The stomata opens at night to store CO2 as C4 so that photosynthesis can happen during the day
