To conserve water, the stomata of CAM plants open during night to take up CO₂ and store it in the form of malic acid which is utilised during the time of photosynthesis.

Correct Option: D

To conserve water, the stomata of CAM plants open during night to take up CO₂ and store it in the form of malic acid which is utilised during the time of photosynthesis.

Sugarcane is a C₄ plant in which CO₂ is fixed in malic acid by the enzyme phosphoenol pyruvic acid carboxylase present in mesophyll cells.

Correct Option: C

Sugarcane is a C₄ plant in which CO₂ is fixed in malic acid by the enzyme phosphoenol pyruvic acid carboxylase present in mesophyll cells.
