Flowers and pollination – basic principles
How it works
Flowers are the reproductive organs of flowering plants. They usually consist of sepals, petals, stamens (male, with pollen) and carpels (female, with stigma, style and ovary). Pollination is the transfer of pollen to the stigma of a flower. It can occur by wind, insects or other animals; rarely, water pollination also occurs. After pollination, fertilization can take place, in which the male sperm cell fuses with the female egg cell. Many plants depend on specific pollinators, while others self-pollinate or are pollinated by wind.
Note
Pollination is the process in which pollen is transferred from the stamens to the stigma of a flower. This can happen, for example, by wind, animals or, rarely, also by water and can lead to fertilization. The flower organs each have specific functions.
