Question

Write short note on adaptations of desert plants and animals.

Hint:

Xerophytes and desert animals survive mainly by water conservation strategies.

Answer 1

Step 1: Adaptations of desert plants (xerophytes).
- Thick cuticle and reduced leaves (spines) to minimize water loss.
- Stomata sunken or reduced in number.
- Photosynthesis through stems (e.g., cactus).
- Deep root systems to absorb groundwater.

Step 2: Adaptations of desert animals.
- Nocturnal lifestyle to avoid daytime heat.
- Ability to store water in body tissues (e.g., camel's hump stores fat).
- Concentrated urine and dry feces to conserve water.
- Burrowing habits to escape extreme heat.

Final Answer:
\[ \boxed{\text{Desert plants and animals show structural, physiological, and behavioral adaptations to conserve water and survive in hot, dry conditions.}} \]
