Question

Where do plants that use CAM photosynthesis usually reside and how do they reduce water loss?

a) Tropical rainforests; high transpiration rates
b) Deserts; opening stomata at night
c) Temperate forests; closing stomata during the day
d) Alpine regions; reducing chlorophyll content
e) Grasslands; increasing leaf surface area

Answer 1

Desert plants that use CAM photosynthesis open their stomata at night to reduce water loss and take up carbon dioxide.

Step-by-step explanation:

Plants that use CAM photosynthesis usually reside in deserts.

To reduce water loss, these plants have adapted by opening their stomata at night when it is cooler and more humid. This allows them to take up carbon dioxide (CO₂) while minimizing water loss through transpiration. During the day, the stomata are closed to conserve water.
