Question

name the following---[b]plants in which lenticular transpiration

Answer 1

Transpiration is the process of water loss from leaves of plants through stomata. Transpiration mostly occurs in leaves through special structures present on them called as stomata. Transpiration always occurs against the gravity. Transpiration involves mainly the xylem cells which become active during absorption process by the roots. *Lenticular transpiration is the type of transpiration which occurs through the small pores called as lenticels present in the bark. It constitutes about 15%-20% of total transpiration. It occurs throughout the day and night. Lenticels  are horizontal striations which occur between the dead cells of the periderm. These are dead and are exterior to bark. As the layer above the bark is dead, these lenticels help in the exchange of gases through dead areas.
