Answer:

When a grain of pollen reaches the stigma, it creates a pollen tube for the sperm of journey down the style and fertilized ovules become seeds. Fertilization of the death of flower, as the petals drop or wither as this point and the ovary start to enlarge and ripen into as fruit.

Answer:

Pollination

The first step in the flower-to-fruit process is pollination. Most fruit-bearing species are pollinated by insects, but birds, bats and wind can also also assist in pollination. Some species, like peaches (Prunus persica), are self-fertile, meaning that pollen from one flower on a specific tree can pollinate another flower on the same tree. Other species, like apples (Malus pumila), require the presence of several varieties of fruit trees for successful cross-pollination.

Fertilization

When a pollinator deposits a grain of sperm-containing pollen on a flower's stigma -- part of the pistil or female reproductive organ -- the grain of pollen produces a pollen tube through which the sperm travels down the flower's hollow stile to the rounded ovary at the base. The ovary contains eggs, or ovules, which are fertilized by the sperm to form seeds. Once fertilization occurs, the petals wither, eventually falling away. The ovary, containing the fertilized ova, begins to swell into an immature fruit.

Ripening Fruits

Over the course of the growing season, the fruit swells, increasing in size and usually changing color as well. As this ripening process occurs, the young fruit is vulnerable to damage from wind, rain or hail. It may also be attacked by pests or diseases. In the wild, plants generally produce enough flowers for abundant fruiting, thereby ensuring that seed is dispersed, even if the parent plant suffers damage. Cultivated plants may be bred for increased pest and disease resistance and may also be treated with natural or man made substances to deter pests and diseases.

Fruit Maturity

When fruit is mature, some or all of it is harvested and eaten, either by birds, animals or humans. The fruit eaten by birds and animals passes through their digestive tracts and the seeds are secreted, thereby planting a new generation of seedlings, a process that eventually leads back to the flower-to-fruit cycle. Uneaten fruits drop to the ground, where the fleshy pulp degrades, allowing the seeds to come in contact with the soil and possibly germinate.
