Explain the structure of a stamen.

(N/A) stamen is the male reproductive organ of a flower. It consists of two main parts:
$1$. Filament: It is the long,slender,stalk-like structure that supports the anther.
$2$. Anther: It is the terminal,generally bilobed structure. Each lobe typically has two thecae,making it dithecous. The anther is a four-sided structure consisting of four microsporangia located at the corners,two in each lobe. These microsporangia develop into pollen sacs,which contain pollen grains.
