Desert plants like cactus grow in deserts because they need less water
It is very spikie and gets less water .
Plants found in deserts are well adapted to cope with harsh desert conditions such as water scarcity and scorching heat. 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 entirely modified into spines and photosynthesis is carried out by green stems. Desert plants have special pathways to synthesize food, called CAM (Cpathway). It enables the stomata to remain closed during the day to reduce the loss of water through transpiration.
