How fruit is formed in flowering plant?
Answers
Answer:
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.
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
Abundant flowers on a fruit tree are harbingers of a good harvest.
Every fruit begins with a flower, but not every flower results in a fruit. The journey from flower to fruit involves variables including weather and climate conditions that favor the development and ripening of fruits, the presence of pollinating insects and in some cases, the availability of a pollinating partner specimen. Changes in any of those variables will result in fewer flowers, fewer fruits or poorer quality fruits. Some factors, like the availability of a pollinating partner specimen, can be controlled. Others, like weather, cannot.
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.
Answer:
A fruit is formed by flowering plant when fertilization occurs then the ovary of the plant swell to form a fruit.
If you think it's not accurate, it's fine because I'm just a student. :PPP
