Question

Choose the correct statement that explains the role of CAM (Crassulacean Acid Metabolism) in plants?

• A. CAM allows plants to produce more glucose from a given amount of raw material
• B. CAM allows plants to carry out photosynthesis without the use of water
• C. CAM allows plants to take in carbon dioxide at night instead of during the day
• D. CAM allows plants to keep their stomata open at all times
• E. CAM allows plants to conserve energy in cold climates

Answer 1

The correct option is C CAM allows plants to take in carbon dioxide at night instead of during the day

CAM or Crassulacean Acid Metabolism is a photosynthetic process found in plants living in arid habitats. The carbon fixation pathway in CAM photosynthetic process is an evolved one adapted to meet the arid conditions wherein the stomata in the leaves remain closed during the day so as to reduce evapotranspiration, but are open at night to collect carbon dioxide.

So, the correct answer is option C.
