Sexual propagation is the method by which plants reproduce using seeds. This process results in new plants that are similar, but not identical, to their parent plants. Pollination involves the transfer of pollen from the male stamen to the female stigma, where fertilization occurs in the ovary. The fertilized ovum transforms into a seed, while the plant reserves food for the seed's development. Eventually, this process leads to the formation of fruit, which encases the seeds. Wind, insects, birds, and animals all play a role in pollination.

What is it? • Sexual propagation is the production of plants from seeds. • The new plants are not exactly the same as the parent plants, but they are close enough for most uses.
Exchange Gametes in Plants • Pollen from male flowers is carried from the stamen to the stigma of a flower. • The pollen then moves down the style to the ovary where the ovum is fertilized. Anther Pollen Grain Style Pollen Tube Filament Ovary Ovule
The pollen may be carried to the stigma by wind, insects, birds, or animals. Pollen Carriers
After pollination..... • The ovum becomes a seed. • The plant begins to store food for the seed. • Fruit is made.
