Detailed explanation-1: -A stamen is composed of a filament and an anther. The filament is a long stalk-like structure which supports the anther. The anther is a two-lobed structure which contains microsporangia for the production of pollen grains.

Detailed explanation-2: -The stamen is the male reproductive organ of the flower (Fig. 1A). It consists of two parts: the anther and a supporting filament.

Detailed explanation-3: -The male parts are called stamens and usually surround the pistil. The stamen is made up of two parts: the anther and filament. The anther produces pollen (male reproductive cells). The filament holds the anther up.

Detailed explanation-4: -The male reproductive parts of the flower include the anther and filament. These two structures make up the stamen. In contrast, the female reproductive parts of the flower include the stigma, style, and ovary. These three parts make up the pistil.

Detailed explanation-5: -The anther consists of four saclike structures (microsporangia) that produce pollen for pollination. Small secretory structures, called nectaries, are often found at the base of the stamens; they provide food rewards for insect and bird pollinators.
