Which among the following adaptation is done by plants to survive in desert area?

Which among the following adaptation is done by plants to survive in desert area? Correct Answer Photosynthesis by steam

Concept:

  • Dessert is an area that receives scarce rainfall hence pertains to a continuous condition of dry environment.
  • By saying dry environments, desserts have very little water around. 
  • A desert is thus called a barren section of the environment with minimal precipitation.
  • High temperatures combined with a lack of water make life difficult for plants in the desert.
  • For survival, plants show different kinds of adaptations to best suit their immediate environment. 
  • Different adaptations are - 
    • The roots of these plants penetrate deeper within the soil to find and absorb more water.
    • Leaves are in the form of needles and are very thin to prevent loss of water and provide protection from predators.
    • Stems are fleshy to store water and food.
    • Stems are modified and become green to perform photosynthesis. 
    •  A waxy layer surrounds the plant body to prevent loss of water too. 

Explanation:

  • In desert plants, for survival, they show different adaptations.
  • The leaves do not perform photosynthesis and thus the stems that become fleshy perform this process. 
  • Hence the correct answer to this question is - Photosynthesis by stems.
