Transpiration is a necessary evil in plants. Explain.

(N/A) Transpiration is considered a 'necessary evil' because it is an inevitable process that has both advantages and disadvantages for the plant.
$1$. Necessity: It is essential for the absorption and upward movement of water and minerals from the soil to the leaves (transpiration pull). It also helps in cooling the leaf surface and maintaining the turgidity of plant cells.
$2$. Evil: It leads to a significant loss of water. If the rate of transpiration exceeds the rate of water absorption by the roots,it causes water stress,leading to wilting,physiological damage,and potentially the death of the plant.
