Question

Identify incorrect statement about CAM Plants

• A. CAM plants show scotoactive type of ofomata
• B. CAM plants show CO₂ fixation in two kinds of cells
• C. CO₂ is fixed during night and glucose is made during day
• D. CO₂ fixation and calvin cycle are separated by time

Answer 1

The correct option is B

CAM plants show CO₂ fixation in two kinds of cells

Succulents possess scotoactive stomata that close during day and open during night. $C{O}_2$ is fixed during night and glucose is synthesized during day in the same cell. In terms of overall goal of reducing photorespiration, CAM is similar to $C_4$ pathway.
