Answer 1

Answer:

A lenticel is a porous tissue which possesses cells with large intercellular spaces in the periderm of the secondary organs and the bark of woody stems. It functions as a pore and participates in the direct exchange of gasses between the internal tissues and atmosphere through the bark, which is otherwise impermeable to gasses.

The main function of lenticel is to perform a gaseous exchange between air and inner tissues
