Question

Why is anther called as fertile part of stamen

Answer 1

Answer:

Stamen is the one of the  male reproductive part of a flower.A stamen typically consists of a stalk called the filament and an anther which contains microsporangia.Collectively the stamens form the androecium.

Anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands.It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte.
