The water lost during transpiration is a side effect of the plant's exchange of gases. However, the plant derives some benefit from this water loss in the form of .

Cooling effect, mineral transport, osmotic balance and gaseous exchange.

Explanation:

The evaporation of water through transpiration in plants produces cooling effect. The high energy molecule will leave the plants in evaporation leaving behind the low energy molecules. That will reduce the tempertature.

The transpiration of water creates the suction pressure that helps in transportation of minerals.

The transpiration helps in osmotic balance through the loss of excessive water.

Transpiration also helps in exchange of gases by the opening of stomata in leaves.
