Production of new plants
Plant propagation is the production of new plants naturally or by artificial methods.
After fertilisation in flowering plants, the fertilised ovule develops into a seed. The seeds of many flowering plants have the following structure.
The component parts of a fertilised ovule as it is turning in to a seed
| Part of seed | Function |
| Embryo | Grows and develops into a new plant by producing shoots and roots |
| Food store (mainly starch) | Provides energy for the embryo to grow. The embryo does not carry out photosynthesis because there is no light. |
| Seed coat | Protects the embryo and prevents it drying out |
