Endothecium has hygroscopic nature. The inner tangential walls are unable to stretch as the anther matures, because of fibrous thickenings but the outer walls are thin and hygroscopic because of which they can expand by absorbing water as the anther matures.31-Ma
The cells of endothecium are radially elongated and develop fibrous thickenings which arise from inner tangential walls, at maturity. These fibrous thickenings are made up of alpha cellulose and traces of lignin. The outer tangential walls remain thin. Endothecium has hygroscopic nature. The inner tangential walls are unable to stretch as the anther matures, because of fibrous thickenings but the outer walls are thin and hygroscopic because of which they can expand by absorbing water as the anther matures. Due to this uneven and differential expansion of outer and inner tangential walls, and the hygroscopic nature of endothelial cells, the endothecium helps in anther dehiscence at maturity.
