Transpiration Quiz Test | What is transpiration in biology?

Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere. Transpiration is essentially evaporation of water from plant leaves. best of luck.....
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.

What is transpiration in biology? Transpiration is the process where plants absorb water through the roots and then give off water vapor through pores in their leaves. An example of transpiration is when a plant absorbs water in its roots.
