How are cactus adapted to survive in deserts?


To survive in deserts, a cactus has the following adaptation-

• Leaves either absent or modified into spine to reduce water loss from the leaves through transpiration.


• Stem is modified to perform photosynthesis.


• Stem is covered by a thick waxy layer that helps to retain water.


• Root system is well developed and goes very deep into the soil for absorbing water.
