Question
Which layer of the microsporangium wall helps in the dehiscence of the anther to release pollen by developing fibrous thickenings?
Explanation
The Endothecium (the layer below the epidermis) develops fibrous bands of alpha-cellulose. These bands are hygroscopic and help in the dehiscence (splitting) of the anther when it dries up, releasing the pollen.
