Describe Formation of Lenticel - QS Study
QS Study

On the bark of woody plants, there are some lens shaped or egg shaped pores present called lenticel.

Formation:

i) For the convenience of gaseous exchange cork cambium, in different places, produces thin walled round parenchymatous cells instead of cork tissue.

ii) Due to the formation of parenchymatous cells, cell division occurs rapidly in them. Thus, a pressure falls on epidermal tissue and the epidermal cells rupture and form lens shaped pores

iii) The parenchymatos cells below the lens shaped pores are known as complementary cells. These lens shaped pores and the area of complementary cells ling below the lens shaped pores are known as lenticels.

Functions:

i) The main function of lenticel is to perform gaseous exchange between air and inner tissues.

ii) Often a little transpiration may occur through lenticel.
