Which type of pollination occurs when pollen from the stamen of one flower pollinates a flower of the same plant?

Pollination is the process by which pollen is transferred in plants, thereby enabling fertilization and sexual reproduction. Pollen grains, which contain the male gametes (sperm) to where the female gamete(s) are contained within the carpel;[1] in gymnosperms the pollen is directly applied to the ovule itself. The receptive part of the carpel is called a stigma in the flowers of angiosperms. The receptive part of the gymnosperm ovule is called the micropyle. Pollination is a necessary step in the reproduction of flowering plants, resulting in the production of offspring that are genetically diverse.
The study of pollination brings together many disciplines, such as botany, horticulture, entomology, and ecology. The pollination process as an interaction between flower and vector was first addressed in the 18th century by Christian Konrad Sprengel. It is important in horticulture and agriculture, because fruiting is dependent on fertilisation, which is the end result of pollination.

What is self pollination and cross pollination?
If the pollen lands on stigma of the same flower, it is called self-pollination. When the pollen of a flower lands on the stigma of another flower of the same plant, or that of a different plant of the same kind, it is called cross-pollination.
Hummingbirds drink nectar from flowers. As they pass from flower to flower the hummingbirds carry pollen aiding in pollination. What kind of relationship exists between the hummingbirds and the flower?
mutualism
What makes a humming bird drinking pollen mutualism?
A Humming bird Benefits from Drinking the flowers because the flower comes like food to the Humming Bird.The flower Benefits from the Humming bird because the humming Bird pollinates it.
How do bees pollenate?
they pollinate flowers by going to a flower and getting the nectar the bee wants and there foot falls into a sac that holds the pollen and the and then when the bee leaves the flower and goes to another flower the pollen falls off the bees foot and starts the pollination process
How do animals help pollination?
Most animals actually don't realize that they are helping the pollination of a plant. For example, a bee usually lands on a flower to take some nectar, but its body unintentionally takes some pollen along and then, while they are flying to another flower, spread the pollen to the pistil of the second flower (or sometimes also of the first flower). Animals have a large role in pollination. Most pollinations happen because of animals like bees. Some are also caused by the wind, but if there isn't any animals helping the pollination, it would be hard for the seeds to grow.
Can someone help me use pollination self-pollination and cross-pollination in the same sentence?
Self pollination is when a flower pollinates itself with its own pollen and cross pollination is when a flower uses another flower's pollen.
Where does pollination in the flower occur?
pollination occurs when the pollen grains are transported from the anther to stigm hello navith
Explain the difference between crosspollination and self pollination in plants?
Cross pollination is when pollination occurs between two different varieties of plant, which do not ordinarily pollinate each other, thus producing a new, hybrid variety of plant. Self pollination is when a single plant pollinates itself, thus there is no mixing of genetic material, the offspring will have only one parent instead of two.
What is the difference between pollination and fertilization in angiosperm?
Pollination is the spreading of pollen from the male to the female part of a flower. Fertilization is the sperm and egg joining to form a zygote and occurs in animals.
What is self pollination?
Self pollination is the dropping of pollen on the stigma of the same flower that produced the pollen, thereby pollinating the flower.
Differentiate cross pollination from self pollination?
Self pollination is where the plant is able to pollinate without another plant. This provides much less variation in the genetics of the species from generation to generation than cross pollination which is where the pollen from one plant is carried to another plant (bees usually do this) and fertilizes the other plant. It creates more genetic diversity because the genes from both plants, which are different, are involved in the forming of the seed, not just the genes from the one self-pollinating plant.--------------------------------------------IMPROVEDSelf pollination is the transfer of pollen from the anther to the stigma of the same flower, another flower on the same plant, or the flower of a plant of the same clone. Cross pollination is the transfer of pollen from the flower of one plant to the flower of a plant having a different genetic constitution.
How does cross pollination happens?
it occurs naturally through insects.When an insect sits in a flower the pollen gets attached to its legs.th pollen is transferred when it sits on another plant and pollination occur
What is the difference between germination and pollination?
Pollination occurs when pollen reaches the pistil (female parts) of the flower. Fertilization occurs when the sperm cells of the flower fuses with the egg. Germination happens when the conditions are right the plant embryo germinates and begins to develop into a young plant. It is the only stage that does not include fertilization. Pollination is the first step fertilization the second and germination the third and final step.
What is self pollination and cross pollination?
If the pollen lands on stigma of the same flower, it is called self-pollination. When the pollen of a flower lands on the stigma of another flower of the same plant, or that of a different plant of the same kind, it is called cross-pollination.
What process moves pollen from flower to flower?
Pollination
When does pollination take place?
A flower is pollinated when a bee drinks it's nectar. The bee will have pollen (a dust like substance) trapped on the hairs of it's legs from other flowers. Pollen from the flower gets trapped on the bee, and pollen trapped on the bee's legs get in the flower. This is how a flower is pollinated.
What is The transfer of pollen grain occurs in the same flower or between two flowers of the same plant called?
pollination
