Detailed explanation-1: -Stamen is the male reproductive part of the flower. It consists of two parts, anther and filament. Anther (pollen sac) is a bulb like structure which contains the pollen grains. Filament is the stalk of the stamen.

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: -…a long slender stalk, the filament, with a two-lobed anther at the tip. The anther consists of four saclike structures (microsporangia) that produce pollen for pollination.

Detailed explanation-4: -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.

Detailed explanation-5: -Filament. The thin stalk that supports the anther in the male portion of the flower.
