What happens when a plant fertilizes?
Fertilization occurs when one of the sperm cells fuses with the egg inside of an ovule. After fertilization occurs, each ovule develops into a seed. Each seed contains a tiny, undeveloped plant called an embryo. The ovary surrounding the ovules develops into a fruit that contains one or more seeds.
What are self pollinating plants called?
In order for self-pollination to occur, plants must be monoecious, which means that there are both male and female parts present in the flowers of one plant. Dioecious plants produce male and female flowers on separate plants, and they require cross-pollination for the production of seeds and fruits.
How do plants fertilize themselves?
Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Self-pollination occurs in flowers where the stamen and carpel mature at the same time, and are positioned so that the pollen can land on the flower’s stigma.
What is the process called when a plant is Fertilised by an insect?
During plant reproduction, pollen grains need to move from the anther of one flower to the stigma of another flower. This is called pollination . Insects can pollinate flowers, and so can the wind.
What is pollination by wind called?
Anemophily is the process when pollen is transported by air currents from one individual plant to another. About 12% of the world’s flowering plants are wind-pollinated, including grasses and cereal crops, many trees, and the infamous allergenic ragweeds.
What happens to stamens after fertilization?
Just after the fertilization, some parts of the flower may fall off and remain intact while some are transformed. The ovary of the flower gets enlarged and forms the fruit while the ovarian wall forms the fruit wall. The stamens, style, petals, and stigma of the flower fall off as they are no longer required.
What is meant by Autogamy?
Autogamy, the production of gametes by the division of a single parent cell, is frequently found in unicellular organisms such as the protozoan Paramecium. These organisms, however, may also reproduce by means of conjugation, in which cross-fertilization is achieved by the exchange of genetic material…
What is cross pollination called?
Allogamy is also known as cross pollination in which pollen grains are transferred from the anther to the stigma of the flower borne on a separate plant of the same species.
What is another name for self fertilizing?

What is self reproduction called?
Asexual reproduction is a process by which organisms create genetically similar or identical copies of themselves without the contribution of genetic material from another organism.
What is pollination article?
Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma. The goal of every living organism, including plants, is to create offspring for the next generation. One of the ways that plants can produce offspring is by making seeds.
What is insect pollination called?
entomophily
Pollinators range from physical agents, especially the wind (wind pollination is called anemophily), or biotic agents such as insects, birds, bats and other animals (pollination by insects is called entomophily, by birds ornithophily, by bats chiropterophily).
