- PARTS OF A FLOWER
Here are the definitions and functions of each term:
1. Petal:
- Definition: The colorful, often delicate part of a flower that attracts pollinators such as insects and birds.
- Function: Petals serve to attract pollinators to the flower, aiding in the process of pollination.
2. Anthel:
- Definition: The collective term for all the petals of a flower.
- Function: Anthels collectively form the outermost whorl of the flower and serve to attract pollinators.
3. Filament:
- Definition: The thin stalk-like structure that supports the anther of a flower.
- Function: Filaments hold the anthers in position, ensuring that they are properly positioned for pollen release.
4. Stamen:
- Definition: The male reproductive organ of a flower, consisting of the filament and anther.
- Function: Stamen produces and releases pollen, which contains the male gametes necessary for fertilization.
5. Sepal:
- Definition: The leaf-like structures that form the outermost whorl of a flower, enclosing and protecting the inner reproductive structures.
- Function: Sepals protect the developing flower bud and play a role in attracting pollinators.
6. Stigma:
- Definition: The sticky, often bulbous structure located at the tip of the style in the center of the flower.
- Function: Stigma serves as the receptive surface for pollen grains during pollination, facilitating the transfer of male gametes to the o***y.
7. Style:
- Definition: The slender, elongated structure that connects the stigma to the o***y in the center of the flower.
- Function: Style provides a pathway for pollen tubes to grow towards the o***y after pollination, facilitating fertilization.
8. O***y:
- Definition: The enlarged, basal portion of the pistil that contains the ovules and eventually develops into a fruit after fertilization.
- Function: O***y houses the ovules, which contain the female gametes, and serves as the site of fertilization and subsequent fruit development.
9. Ovule:
- Definition: The structure within the o***y of a flower that contains the female gametophyte and eventually develops into a seed after fertilization.
- Function: Ovules contain the female gametes and serve as the site of fertilization, leading to the formation of seeds.
10. Carpel:
- Definition: The female reproductive organ of a flower, consisting of the stigma, style, and o***y.
- Function: Carpel produces ovules and serves as the site of fertilization and seed development in flowering plants.
11. Pollen grain:
- Definition: The microscopic structure produced by the anther of a flower, containing the male gametes (s***m cells).
- Function: Pollen grains are responsible for transferring male gametes from the stamen to the stigma during pollination, facilitating fertilization.
