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 ...

The synstigma arrangement was quite variable: lax, cohesive or very cohesive, with entanglement by stigmatic papillae and stylar trichomes.

Oct 17, 2024 · Quick Reference. 1 The glandular sticky surface at the tip of a carpel of a flower, which receives the pollen. In insect-pollinated plants the stigmas are held within the flower, whereas in wind-pollinated species they hang outside it. 2 See eyespot. From: stigma in A Dictionary of Biology ».
