Detailed explanation-1: -Transpiration results in water scarcity that can damage the plants due to desiccation. It also causes wilting of the leaves and results in stunted growth of the plants.

Detailed explanation-2: -(b) Excessive transpiration results in the wilting of the leaves.

Detailed explanation-3: -Excessive rate of transpiration leads to stunted growth of plants. Since approximately 90 percent of absorbed water is lost through transpiration, the energy used in absorption and conduction of water goes waste.

Detailed explanation-4: -Through evaporative cooling, plant transpiration brings down the temperature of leaves, the largest plant organ. 4. Water balance in plants is also maintained by transpiration. Plants absorb a lot of water and transpiration is a means by which excess water is removed.
