________________ is a wasteful pathway that occurs when the Calvin cycle enzyme rubisco acts on oxygen rather than carbon dioxide.

• Respiration

• Photo-transpiration

• Photorespiration

• None of the answers are correct

Some plants use the crassulacean acid metabolism (CAM) pathway to minimize photorespiration.

• True

• False

How do CAM plants minimize photorespiration?

• the Calvin cycle and light dependent reactions happen at different times of the day.

• the Calvin cycle and light dependent reactions happen in different cells

• none of the answers are correct

In C3 plants, the light-dependent reactions and the Calvin cycle are physically separated, which minimizes photorespiration.

• true

• false

The majority of plants are C3 plants

• True

• False

C4 plants are often more effecient at photosynthesis because the light dependent reactions and the Calvin cycle are physically separated. Light dependent reactions occur in mesophyll cells and the Calvin cycle occurs in the _______________ cells .

• chlorenchyma

• sclerenchyma

• epidermal

• bundle-sheath cells

the light dependent reactions occur in the _______________.

• stroma

• chlorophyll

• mitochondria

• thylakoid

The light independent reactions occur in the _______________.

• stroma

• chlorophyll

• mitochondria

• lumen
