Question

Does endothecium absorb or loose water during dehiscence of anther?

Answer 1

It will loose water.

Endothecium is a type of tissue foundthe walls of anthers and in moss capsules. This tissue is usually one toseveral layers thick, and is composed of cells that have walls of uneven thickness.In anthers, the endothecium isresponsible for the tensions that lead to anther dehiscence or splitting. It is the uneven thickness of the cells wallsthat cause this. The cells lose water, and the uneven thickness causes the thinner walls of the cells to stretch to agreater extent. This creates a tension that eventually leads to the anther being split along its line of weakness andreleasing pollen grains to the atmosphere
