Question 2:

How is cactus adapted to survive in a desert?

Answer:

Cactus loses very little water through transpiration. The leaves in cactus plants are present in the shape of spines. This helps in reducing loss of water from the leaves through transpiration. Its stem is converted into a leaf-like structure. Photosynthesis in these plants is usually carried out by the stems. The stem is also covered with a thick waxy layer, which helps to retain water. Cactus plants have roots that go very deep into the soil for absorbing water.
