Q. Consider the following adaptive features of desert plants:

1. Leaves are absent or reduced in size in desert plants.
2. Leaves and stems are succulent and store water.
3. The root system is well-developed and spread over a large area.

Which of the above adaptations help desert plants conserve water?
Answer: 1, 2 and 3
Notes: All three statements are correct. Desert plants often have absent or reduced leaves to minimize water loss, possess succulent tissues in leaves and stems for water storage, and exhibit well-developed and widespread root systems to maximize water absorption from the soil. These adaptations collectively enable them to survive in arid environments with minimal rainfall.
