Detailed explanation-1: -Stamen is the male reproductive part of a flower. It consists of an anther and filament. The bulged part of stamen which produces pollen grain is known as anther which is borne on a slender stalk known as filament.

Detailed explanation-2: -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. Small nectaries are found at the base of stamens which provide food for insect and bird pollinators.

Detailed explanation-3: -Filament. The thin stalk that supports the anther in the male portion of the flower.

Detailed explanation-4: -Each stamen consists of a stalk called the filament and a small bag like structure called the anther at the tip.

Detailed explanation-5: -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. During the process of fertilization, pollen lands on the stigma, a tube grows down the style and enters the ovary.
