Question

Transpiration is a necessary evil.give reason.

Answer 1

The loss of water in the form of vapors from aerial parts of the plant is called transpiration. Transpiration is a necessary evil because it is an inevitable, but potentially harmful, consequence of the existence of wet cell surfaces form which evaporation occurs. Loss of water from the plant results wilting, serious desiccation and often death of a plant if a condition of drought is experienced. There is strong evidence that even mild water stress results in reduced growth rate and in crops to economic losses through reduction of yield.
