$\Huge\purple{\mathfrak{\underline{\underline{answer}}}}$

→ Stomatal Transpiration

*It occurs through minute pores called stomata present in epidermis of young stem and leaves.

*Loss of water through stomata is called stomatal transpiration.

*Opening and closing of stomata occurs due to osmotic changes in guard cells.

*When the guard cells are turgid, the Stomata get opened.

*When guard cells become flaccid, the Stomata get closed.

→Lenticular transpiration

* It occurs through the lenticels present in the bark of old stems and pericarps of woody fruits.

* Lenticels are fine pores composed of loosely arranged cells called complementary cells.

* It occurs throughout day and night.
