प्रश्न
How will you differentiate the different types of transpiration?

उत्तर
There are three types of transpiration:
Stomatal transpiration: Loss of water from plants through stomata. It accounts for 90- 95% of the water transpired from leaves.
Cuticular transpiration: Loss of water in plants through the cuticle.
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 continuous supply of minerals.
- It regulates the temperature of the plant.
