Answer 1

Option (d).

The presence of specific features, which enable a plant or an animal to live in a particular habitat is called adaptation. Adaptations of desert plants that help them to survive in the desert are:

• Leaves are very small or reduced to spines and hence they lose very little water through transpiration.
• The stem is covered with a thick waxy layer to retain water.
• Their roots grow very deep into the soil for absorbing water.
