Question

Deserts are dry, hot habitats with very little water content in the soil. How do the desert plants manage their water requirements in such habitats?

• A. Have broad leaves.
• B. Deep penetrating roots.
• C. Leaves modified into spines.
• D. Waxy coating on the leaves.

Answer 1

Answer: (B), (C), (D)

The correct options are
B Deep penetrating roots.
C Leaves modified into spines.
D Waxy coating on the leaves.

The desert plants have adapted to such extreme habitats as follows.
-The leaves are modified into spines which decreases the surface area of leaves, causing less water loss through transpiration.
-The thick cuticle on their leaves also prevents water loss through transpiration.
-Huge water holding capacity in the plant body.
-The roots penetrate deeply in the soil to absorb water.
