5 science - Pollination
| Term | Definition |
|---|---|
| Flower | The reproductive part of a plant, responsible for producing seeds. |
| Sepals | Green, leaf-like structures that protect the flower bud and support petals; collectively called the calyx. |
| Calyx | The outermost whorl of a flower, composed of sepals. |
| Petals | Often brightly colored or scented parts of a flower that attract pollinators; collectively called the corolla. |
| Corolla | The collective term for all the petals of a flower. |
| Nectar | A sweet, sugary liquid produced by some flowers to attract pollinators. |
| Stamen | The male reproductive part of a flower, consisting of an anther and a filament. |
| Androecium | The collective term for all the stamens in a flower (male part). |
| Filament | The stalk-like part of the stamen that supports the anther. |
| Anther | The part of the stamen that produces and contains pollen grains. |
| Pollen Grains | Tiny, dust-like particles produced by the anther containing male gametes for plant reproduction. |
| Pistil | The female reproductive part of a flower, consisting of stigma, style, and ovary. |
| Gynoecium | The collective term for all the pistils in a flower (female part). |
| Stigma | The sticky tip of the pistil that receives pollen grains. |
| Style | The tube-like structure connecting the stigma to the ovary in a pistil. |
| Ovary | The swollen basal part of the pistil that contains ovules and develops into a fruit. |
| Ovules | Structures within the ovary that develop into seeds after fertilization. |
| Unisexual Flower | A flower that has either male (stamens) or female (pistil) reproductive parts, but not both. |
| Bisexual Flower | A flower that has both male (stamens) and female (pistil) reproductive parts in the same flower. |
| Pollination | The transfer of pollen grains from the anther to the stigma of a flower of the same kind. |
| Pollinators | Agents (insects, birds, bats, wind, water) that transfer pollen between flowers. |
| Titan Arum | Known as the 'corpse flower', it smells like rotting flesh to attract flies for pollination. |
| Horticulture | The science and art of cultivating plants, especially flowers, fruits, and vegetables; the practice of gardening. |
| Self-Pollination | The transfer of pollen from the anther to the stigma of the same flower or another flower on the same plant. |
| Cross-Pollination | The transfer of pollen from the anther of one flower to the stigma of a flower on a different plant of the same species. |
