Solution
Transpiration is considered to be a necessary evil because it leads to the loss of water from plants but provides the plant with several advantages as well.
Creates transpirational pull for transport
Supplies water for photosynthesis
Transports minerals from the soil to all parts of a plant
Cools the surface of the leaves (due to the evaporation of water)
Keeps the cells turgid; hence, maintains their shape.
