Types of transpiration

Types of Transpiration

There are three different types of transpiration in plants:

Stomatal Transpiration

It is the evaporation of water from the stomata of the plants. Most of the water from the plants is transpired this way. The water near the surface of the leaves changes into vapour and evaporates when the stomata are open.

Lenticular Transpiration

Lenticels are minute openings in the bark of branches and twigs. Evaporation of water from the lenticels of the plants is known as lenticular transpiration.

Lenticels are not present in all the plants. A minimal amount of water is lost through lenticels.

Cuticular Transpiration

It is the evaporation of water from the cuticle of the plants. The cuticle is a waxy covering on the surface of the leaves of the plants. About 5-10% of the water from the leaves is lost through cuticular transpiration. During dry conditions when the stomata are closed, more water is transpired through the cuticles.
