AP BIOLOGY

Detailed explanation-1: -Style-is a long slender stalk that holds the stigma. Once the pollen reaches the stigma, the style starts to become hollow and forms a tube called the pollen tube which takes the pollen to the ovaries to enable fertilization. Stigma– This is found at the tip of the style. It forms the head of the pistil.

Detailed explanation-2: -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 supports the stigma. The style leads down to the ovary which contains the ovules. During the process of pollination, pollen moves from the male parts to the female parts.

Detailed explanation-3: -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-4: -The bottom of the pistil contains the ovary and the narrowed region in between is called the style. The male contribution or pollen is produced in the anther, and seeds develop in the ovary.

Detailed explanation-5: -structure of pistil A slender stalk called the style often connects the ovary and stigma.
