Both A and R are true and R is the correct explanation of A. Transpiration is a necessary evil. It is so because water is lost in the form of vapours from the aerial parts of the plant through transpiration. But, it helps in absorption and upward movement of water and minerals creating transpiration pull.

Direction: The following question consists of two statements - Assert...
Assertion: Transpiration is a necessary evil.
Reason: It causes water loss but helps in absorption and upward movement of water and minerals.
The correct answer is option 'A' - Both A and R are true and R is the correct explanation of A.
Explanation:
- Transpiration is a process by which water is lost from the leaves of plants through tiny pores called stomata. It is a necessary process as it helps in the absorption and upward movement of water and minerals through the plant.
- Transpiration facilitates the absorption of water and minerals from the soil, which is essential for the growth and development of the plant.
- In addition to absorption, transpiration also helps in the cooling of the plant. During transpiration, the water evaporates from the leaves, which helps in reducing the temperature of the plant.
- However, excessive transpiration can lead to water loss, which is not desirable. It can lead to wilting and even death of the plant.
- Therefore, transpiration can be considered a necessary evil. It is required for the growth and development of the plant, but excessive transpiration can be harmful.
- The reason provided for the assertion is correct. Transpiration causes water loss, but it is necessary for the absorption and upward movement of water and minerals.
Reason: It causes water loss but helps in absorption and upward movement of water and minerals.
The correct answer is option 'A' - Both A and R are true and R is the correct explanation of A.
