The female part of the flower is called the pistil, which is made up of the stigma, style, and ovary. The stigma is the sticky structure that receives pollen, while the style is the narrow tube that connects the stigma to the ovary, which contains the ovules.
Aug 26, 2024 · The female reproductive organ of a flower, including the stigma, style, and ovary. Stigma – Function: Receives and captures pollen grains, often sticky. – Structure: Located at the top of the style, can vary in shape and texture.

Flowers have two primary parts: the vegetative part, which includes the petals and the sepals, and the reproductive part, encompassing the stamen (male reproductive organ) and the pistil or carpal (female reproductive organ).
The primary function of a flower is reproduction, ensuring the survival of the species. Through the process of pollination and fertilization, flowers produce seeds. Each seed contains a new plant, waiting for the right conditions to grow.
Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma. This process can occur through self-pollination or cross-pollination: 1. Self-pollination: This occurs when the pollen from an anther deposits onto the stigma of the same flower or another flower on the same plant. Self-pollination is common ...

Stamen - The male parts of a flower are called the stamen. Anther - The anther is a part of the stamen that produces and holds pollen. Stigma - The stigma is a sticky part at the top of the female parts of a flower. Ovary - Seeds are formed inside the ovary of a flower.
Jul 27, 2022 · A flower with both androecium and gynoecium — that is both male and female parts — is called perfect or bisexual or hermaphroditic. Perfect flowers may be capable of self-pollination. Pollen produced within the flower may fall on a stigma in the same flower, and the sperm that it carries may fertilize the egg in the ovule.
