Plant Reproduction
Methods of Pollination
Plants can reproduce two ways, via insects or the wind. Insect-pollinated flowers usually have bright colours and a scent to attract the insects while wind-pollinated plants are usually absent of both bright colours and scent. The flower is comprised of many different parts, each with a different function, it's the organ of reproduction in a plant and it's usually hermaphrodite with the ovary deep in the plant.
Flower Structure
NOTE: Not all the plant parts are labelled in the diagram
| Structure | Where? | Function |
|---|---|---|
| Calyx | The outer leaves of the flower, usually green. | To protect the flower. |
| Corolla | A.k.a. the petals, attract insect and protect the carpels and stamen. | Form the outer layer of the flower. |
| Androecium (male organ) | A.k.a. Stamen, which in turn holds the anthers on top | Produces pollen (male gametes) |
| Gynoecium (female organ) | A.k.a. The carpels, an enclosed structure usually central in the flower | Accept pollen and develop ovules. |
