Question

Read the following statement. Write a paragraph about adaptation with reference to the statement.

There is extreme heat in deserts.

Answer 1

There is extreme heat in deserts and dry conditions prevail in this region. The animals and plants which are found in this region have special modifications which help them to survive in such environment. For example, cactus and acacia plants withstand hot and dry environment of the desert with the help of various modifications. They have thick cuticle on their leaf surface and their stomata are arranged in deep pits to minimise water loss by transpiration. They have special photosynthetic pathway, CAM in which stomata remains closed during day time. Their leaves are reduced to spines to minimise water loss, and photosynthetic functions are performed by flattened stems.
Similarly desert animals have adaptive features like-thick skin to prevent the loss of water, long legs with flat and cushioned soles, long and thick eyelashes and nostrils which are protected by folds of skin.
