Detailed explanation-1: -The main function of the pistil is reproduction. Let’s discuss how important it is pistil to the flower: 1) It is the female reproductive part of the flower, and therefore it is involved in the fertilization process. 2) The stigma of the pistil is responsible for receiving the pollen.

Detailed explanation-2: -The pistil is unique to angiosperms. It serves a protective role and functions as a conduit for pollen tubes to grow to the ovary, but it also provides a venue for pollen-pistil interactions that regulate pollen tube growth and, hence, fertilization.

Detailed explanation-3: -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.

Detailed explanation-4: -Pistil: The ovule producing part of a flower. The ovary often supports a long style, topped by a stigma. The mature ovary is a fruit, and the mature ovule is a seed. Stigma: The part of the pistil where pollen germinates.
