Question

Mention any 4 adaptive features that help cactus to survive in xeric condition

Answer 1

first it has thorny body spiny structure helps to survive in desert region

Answer 2

Answer:

• Desert plants have thick waxy coating on leaf called cuticle for minimum loss of water, through transpiration.

• They have special photosynthetic pathway (CAM) that enables minimum loss of water during day time because stomata remain closed.

• Some desert plants develop spines instead of leaf and photosynthetic function is carried out by the flattened stem.  

• Stomata are arranged in deep pits to minimise loss through transpiration.

CAM-Crassulacean Acid Metabolism : it is a photosynthetic adaptation to periodic water supply, occurring in plants in arid regions (e.g., cacti).
