(N/A) Transpiration is often described as a 'necessary evil' because it is an inevitable consequence of the physiological processes required for plant survival.
$1$. It creates a transpiration pull,which is essential for the absorption and upward transport of water and minerals from roots to leaves.
$2$. It provides the necessary water for photosynthesis.
$3$. It cools the leaf surfaces,sometimes by $10$ to $15$ $^{\circ}C$,through evaporative cooling.
$4$. It maintains the shape and structure of plants by keeping the cells turgid.
Therefore,while plants lose a significant amount of water through transpiration,it is an unavoidable process that supports vital functions.
