← Nature & AnimalsWhich consequence is seen in CAM plants when initial carbon fixation exceeds its processing ability inside the cells' vacuoles?
A)Increased photorespiration within mesophyll cells
B)Stomatal closure during light exposure
C)Malate transport inhibition, halting cycle✓
D)Increased transpiration decreases water status
💡 Explanation
In CAM plants, excessive carbon fixation overwhelms its processing capacity inside vacuoles, specifically increasing 'Malate transport inhibition'. This blocks the carbon cycle because increased malate accumulation inhibits further fixation rather than increasing photorespiration or directly affecting water loss.
