Question

Transpiration is useful or harmful to plants

Answer 1

The loss of water in the form of vapour from aerial parts of the plant is calledtranspiration. Transpiration is said to be a necessary evil because it is an inevitable, but potentially harmful, consequence of the existence of wet cell surfaces form which evaporation occurs.

Answer 2

✌️✌️hey mate here is the answer.....

➡️The water, warmed by the sun, turns into vapor (evaporates), and passes out through thousands of tiny pores (stomata) mostly on the underside of the leaf surface.
This is transpiration.
It has two main functions: cooling the plant and pumping water and minerals to the leaves for photosynthesis.

➡️Transpiration is the term used to describe the loss of moisture from a plant.
More than 90% of water escapes from plants through their leaves via tiny openings called stomata.
Temperature: Temperature affects relative humidity because warmer air can hold more moisture.

thanks..
nice to help you ✌️✌️
