A desert plant exhibits a thick waxy cuticle and performs Crassulacean Acid Metabolism (CAM) photosynthesis. A floodplain plant possesses aerenchyma tissue and shallow root systems. If the regional climate shifts to a prolonged drought lasting several months, which plant's adaptation provides a greater survival advantage, and why?

Answer Options

A. The desert plant's thick cuticle actually hinders gas exchange, making the floodplain plant's adaptations more beneficial in prolonged drought.
B. Both plants would survive equally well, as their adaptations are equally effective in conserving water during drought.
Correct Answer C. The desert plant's thick cuticle and CAM photosynthesis provide a greater advantage because they minimise water loss and allow carbon fixation with minimal transpiration.
D. The floodplain plant's aerenchyma tissue and shallow roots provide a greater advantage because they allow rapid water uptake during brief rain events.
Correct Answer
C
Correct Option:
The desert plant's thick cuticle and CAM photosynthesis provide a greater advantage because they minimise water loss and allow carbon fixation with minimal transpiration.
