Definition of Transpiration Review
Transpiration is the process by which plants lose water vapor, mainly through tiny pores called stomata in their leaves. In simple terms, it is how water moves out of a plant after being taken up by the roots and carried upward through the xylem.
[1][9]Quick Scoop
- Main meaning: Water evaporates from plant surfaces and leaves the plant as vapor. [9][1]
- Why it matters: It helps pull water and minerals up from the roots to the shoots. [6]
- In biology revision: It is usually described as the loss of water vapour from leaves by evaporation and diffusion through stomata. [9]
Simple Review
If you are reviewing the definition for class or a post, the clearest version is: transpiration is the loss of water vapour from a plant, especially through its leaves. Researchers also study how transpiration changes with temperature, humidity, and vapor pressure deficit because those factors affect plant water use.
[3][1][6][9]Key Points
- It is a natural plant process, not something harmful by itself. [6]
- It supports water transport inside the plant. [6]
- It is often covered in school biology under plant transport and water balance. [9]
TL;DR: Transpiration is the release of water vapor from plants, mainly through stomata in the leaves.
