Photosynthesis C4 and C3

What does CAM plants store?

• H20

• CO2

• 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

• hot and dry

• both

• none of the above

Why do CAM plants open their stomata at night

• It just happens

• 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

In C3 photosynthesis, the reactions that require ATP take place in

• the light reactions alone

• the calvin cycle only

• both the light reactions and the calvin cycle

• the citric acid cycle

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.

The main problem encountered by C3 plants in hot conditions is:

• Transpiration

• PhotoRespiration

• Dehydration

• Starvation
