Question

How will you differentiate the different types of transpiration?

Answer 1

There are three types of transpiration:
1.Stomatal transpiration:

• Loss of water from plants through stomata.
• It accounts for 90- 95% of the water transpired from leaves.

2.Cuticular transpiration:

• Loss of water in plants through the cuticle.

3.Lenticular transpiration:

• Loss of water from plants as vapour through the lenticels.
• The lenticels are tiny openings that protrude from the barks in woody stems and twigs as well as in other plant organs.

But transpiration is necessary for the following reasons.

• It creates a pull in leaf and stem.
• It creates an absorption force in roots.
• It is necessary for a continuous supply of minerals.
• It regulates the temperature of the plant.
