Plant Adaptation

What do CAM plants store

• water

• oxygen

• sunlight

• carbon Dioxide

what part of the chloroplast does the Calvin cycle take place

• outer membrane

• thylakoid

• stroma

• inner membrane

CAM plants have a different adaptation to what climate

• cold and wet

• arid (very hot/dry)

• hot and wet

• none of the above

Why do CAM plants open their stomata at night?

• To gather sunlight

• To take in oxygen

• To collect Carbon Dioxide

• None of the above

In C4 plants, the Calvin cycle....

• Takes place at night

• Only occurs when the stomata are closed

• Takes place in the mesophyll

• Takes place in the bundle-sheath cells

What are C3 plants?

• These plants are the best when it comes to storing water due to their extremely dry environments

• These plants mostly just reduce the rate of photorespiration

• plants that do the calvin cycle in the mesophyll cells

CAM plants keep stomata closed in daytime, thus reducing loss of water. They can do this because they

• fix CO2 into organic acids during the night when temperatures are cooler.

• fix CO2 into by combining it with RuBP in the Calvin cycle.

• obtain CO2 through their roots during the day.

• fix CO2 into organic acids in the mesophyll cells, which do not rely on stomata.
