Assertion : A typical microsporangium of angiosperms is generally surrounded by four wall layers - epidermis, endothecium, middle layers and tepetum.
Reson : The outer three wall layers perform the function of protection and help in dehiscence of anther to release the pollen.

(i) Microsporangium is generally surrounded by four wall layers-epidermis, endothecium, middle layers and tapetum (ii) outer three layers perform functions of protection and dehiscence of anthers. (iii) Cells of tapetum undergo meiosis and produce micropore tetrads.
