õieorganid
Õieorganid are the reproductive structures of flowering plants, collectively forming the flower. These specialized organs are responsible for the production of gametes and the subsequent process of fertilization, leading to the formation of seeds and fruits. The main components of a typical õieorgan include the calyx, corolla, androecium, and gynoecium. The calyx, composed of sepals, usually protects the developing bud. The corolla, made up of petals, often serves to attract pollinators through its color and scent. The androecium, the male reproductive part, consists of stamens, each with an anther that produces pollen containing male gametes. The gynoecium, the female reproductive part, is typically a pistil or carpel, which includes the stigma, style, and ovary. The ovary contains ovules, each housing a female gamete. Pollination, the transfer of pollen from the anther to the stigma, is a crucial step. Following pollination, fertilization occurs when a male gamete fuses with a female gamete within the ovule. This fusion results in the development of an embryo and the transformation of the ovule into a seed and the ovary into a fruit. The diversity in form and function of õieorganid reflects the evolutionary adaptations of flowering plants to various pollination strategies and environments.
