EXPERT ANSWER

Transpiration is considered to be a necessary or unavoidable evil because it leads to 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 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
