Transpiration is the price which the plant pays for photosynthesis. Give reason

Dear student,
Transpiration plays an important role in the supply of water in photosynthesis and is regarded as a price paid for photosynthesis. A little amount of water (0.2%) is used in the process of photosynthesis. It also helps in maintaining the turgidity of cells and cause transpiration pull in the water column of xylem tissue. The later absorb water along with minerals from soil.

For the process of photosynthesis water is a raw material. Plants use this water to prepare starch.During transpiration there is evaporative loss of water which is paid as a price for the raw material.
