Question
Write a short note on Adaptations of plants to water scarcity
Solution
Adaptations of plants to water scarcity:
Plants found in deserts are well adapted to cope with water scarcity and the scorching heat of the desert.
- Plants have an extensive root system to tap underground water.
- They bear thick cuticles and sunken stomata on the surface of their leaves to reduce transpiration.
- In Opuntia, the leaves are modified into spines and the process of photosynthesis is carried out by green stems.
- Desert plants have special pathways to synthesize food, called CAM (C4 pathway). It enables their stomata to remain closed during the day to reduce water loss by transpiration.
