Question

Write notes on T.S. of typical anther.

Answer 1

If the transverse section of a microsporangium is observed carefully, it is seen that there are 4 layers surrounding the microsporangia:

•Epidermis

•Endothecium

•Middle layers

•Tapetum

The first three ensure protection of the microsporangium, while the innermost layer, Tapetum provides nourishment to the pollen grains.

Sporogenous tissue is present at the centre of each microsporangium.
