BOTANY

Detailed explanation-1: -stamen, the male reproductive part of a flower. 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-2: -Stamen: The pollen producing part of a flower, usually with a slender filament supporting the anther. Anther: The part of the stamen where pollen is produced.

Detailed explanation-3: -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.

Detailed explanation-4: -These stamens are filamentous structures that support the anther that produces the pollen grains. These anthers have two lobes and are termed bilobed anthers. The transverse section of the anther helps to distinguish this bilobed structure. The two lobes of the anther are formed by a septum.

Detailed explanation-5: -Anthers are held up by a thread-like part called a filament. The pistil has three parts: stigma, style, and ovary. The stigma is the sticky surface at the top of the pistil; it traps and holds the pollen. The style is the tube-like structure that holds up the stigma.
