Detailed explanation-1: -The long stalk in stamen is called the filament. Filaments provide support to anthers and they carry nutrients to anthers where pollen develops. In female plants, the stalk-like structure is referred to as the style. It supports stigma and connects to the ovary.

Detailed explanation-2: -The stigma is the sticky knob at the top of the pistil. It is attached to the long, tubelike structure called the style. The style leads to the ovary that contains the female egg cells called ovules. The male parts are called stamens and usually surround the pistil.

Detailed explanation-3: -In all but a few extant angiosperms, the stamen consists of 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 long stalk in stamen is called filament. Filaments provide support to anthers and they carry nutrients to anthers where pollen develop. Solve any question of Sexual Reproduction in Flowering Plants with:-Patterns of problems.

Detailed explanation-5: -Stigma: The part of the pistil where pollen germinates. Ovary: The enlarged basal portion of the pistil where ovules are produced.
