Give a brief account of Lenticular transpiration.

Explanation

In stems of woody plants and trees,the epidermis is replaced by periderm because of secondary growth.In order to provide gaseous exchange between the living cells and outer atmoshphere,some pores which looks.like lens-shaped raised spots are present on the surface of the stem called Lenticles.The loss of water from lemticles is very insignificant as it amounts to only 0.1 % of the total.
