Plants release water vapour into the atmosphere during transpiration.


The process by which plants transport water from their roots through their stems to small pores on the underside of their leaves from which the water is converted to vapour and released is called transpiration.

While water is absorbed by the plant for the purpose of getting dissolved nutrients as well as for metabolism and growth, not all the water is utilised, and hence transpiration is the mechanism whereby the plant disposes of excess water.
