Question

What is transpiration?

Answer 1

Explanation:

Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism. The remaining 97–99.5% is lost by transpiration and guttation.

Answer 2

Answer:

Transpiration is the loss of water in the form of water vapour from leaves and green herbaceous stems through stomata. A large amount of water (about 99%) is lost by plants through this process.
