Key Stage 3 Science (Biology) - Reproduction in Plants
The Science Breakγ»6 minutes read
Plants reproduce through pollination, where male (pollen) and female (egg) sex cells join, facilitated by insects like bees or wind. Fertilization, happening after pollination, occurs when pollen joins an egg in the ovary, leading to seed production in plants through insect pollination.
Insights
- Pollination is the transfer of pollen (male) to egg cells (female) in plants, crucial for reproduction and seed production, achieved through insects like bees or wind.
- Fertilization, a separate process from pollination, occurs when pollen unites with an egg in the ovary, leading to seed formation under favorable circumstances, highlighting plant reproduction via insect pollination.

Plant Reproduction: Pollination, Fertilization, and Seeds
- Plants, like all living organisms, must reproduce for species survival, achieved through the joining of male (pollen) and female (ova or eggs) sex cells, a process known as pollination.
- Pollination can occur through insects, like bees, or wind, where pollen grains are transferred to egg cells, leading to fertilization and seed production.
- Key flower parts involved in reproduction include the male parts - anther and filament, and female parts - stigma and style, with the ovary containing the ovum or egg.
- Fertilization, distinct from pollination, is the process where pollen joins with an egg in the ovary, resulting in seed production under suitable conditions, showcasing plant reproduction through insect pollination.
