AP BIOLOGY

Detailed explanation-1: -The top of the pistil is called the stigma, which is a sticky surface receptive to pollen. 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-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: -The pistil usually is located in the center of the flower and is made up of three parts: the stigma, style, and ovary.

Detailed explanation-4: -Stigma: The part of the pistil where pollen germinates. Ovary: The enlarged basal portion of the pistil where ovules are produced.

Detailed explanation-5: -Anemophilous: Anemophilous pollination is a form of pollination where pollen grains are distributed via wind. In all wind-pollinated flowers, the mature stigma is found rough and sticky.
