Seeds come from flowers, and flowers come from seeds. Seeds are the result of plant reproduction and contain all the necessary ingredients for plant growth. Bees and birds carry pollen to fertilize female flower eggs resulting in seed development.
Germination
Fertilized seeds remain dormant until exposed to water, which is essential to begin the life process. Water fuels cell duplication stretching the seed's outer layer. A taproot shoots down to anchor the new plant and growth begins to ascend out of the soil.
Dispersion
Plants ensure the continuation of species by employing a number of different techniques to scatter seeds. Some seeds have their own built-in wings such as milkweed, while lighter seeds are able to travel via water. Animals carry seeds on their backs, and plants such as violets have a trigger mechanism that shoots seeds up and away. Employing more than one of these methods increases the chance of re-population
Fun Fact
Orchids are members of the asparagus family and have the smallest seeds of any plant.
