Choose the correct option from the given features of desert plants. (A...
Concept:
Desert plants have adapted themselves to survive in arid and hot environments where water is scarce.
Explanation:
- To prevent water loss through transpiration, many desert plants have evolved spines instead of leaves.
- Spines reduce the surface area of the plant, thereby reducing water loss.
- Additionally, deep roots help desert plants reach deeper layers of soil to absorb moisture from the ground.
- On the other hand, the leaves of the cactus are modified into spines, and it performs photosynthesis in its stem instead of leaves, which again reduces water loss.
Therefore, options A and C are correct as they represent the adaptations of desert plants to conserve water.

Features of Desert Plants
Desert plants have adapted uniquely to survive in harsh environments characterized by extreme temperatures and limited water availability. Let's analyze the given statements:
Statement A: Leaves of some plants take the shape of spines.
- This statement is true.
- Many desert plants, like cacti, have modified their leaves into spines to minimize water loss through transpiration.
- Spines also provide protection from herbivores.
Statement B: Photosynthesis in cactus plant is usually carried out by leaves.
- This statement is false.
- In cacti, the leaves are reduced to spines, and photosynthesis is primarily conducted by the stems, which are green and capable of photosynthesis.
- This adaptation helps the plant conserve water while still performing vital functions.
Statement C: Roots of most desert plants go very deep into the soil for absorbing water.
- This statement is true.
- Many desert plants have extensive root systems that can reach deep into the ground to access moisture that is unavailable to surface-level plants.
- Some plants also have shallow roots that spread widely to capture rainwater quickly when it does occur.
Conclusion
Given the analysis, the correct answer is option 'C' because:
- Statements A and C are true, while statement B is false.
- Therefore, the option that includes both true statements (A and C) is the right choice.
Understanding these adaptations is crucial for appreciating how desert flora has evolved to thrive in extreme conditions.
