Photosynthesis Review (C3, C4, CAM)

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

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.

Which of these would be considered a C4 Pathway plant?

• cactus

• sugar cane

• oak tree

• aglae

Which of these would be considered a CAM pathway plant?

• cactus

• corn

• elm tree

• algae

Which type of plant fixes carbon only at night?

• C3

• C4

• CAM

• all of these

Which is not a product of the Calvin Cycle?

• ADP
• NADP+
• G3P
• FADH₂
