transpiration

Definition

Transpiration is the process by which plants lose water through their leaves. Water evaporates from the leaves and enters the atmosphere.

Transpiration is important for plants because it helps to cool them down and to transport water and nutrients throughout the plant.

Here is how transpiration works:

  • Water is absorbed by the roots of the plant and travels up the stem to the leaves.
  • The leaves have tiny pores called stomata.
  • The stomata open and close to control the amount of water that evaporates from the leaves.
  • Water evaporates from the leaves and enters the atmosphere.
  • Transpiration is a continuous process. It happens day and night, even when it is raining.

How can the word be used?

The rate of transpiration is affected by the temperature, humidity, and wind speed.
