Pollination is the process by which pollen grains are transferred from the anther of one flower to the stigma of the same or another flower. Pollen is a substance produced by the pollen of a plant. Nectar, on the other hand, is made up of sugars and other substances that are present in the flowers of plants.

What is pollination answer science?
A pollination is the transfer of pollen grains from anther to stigma of a flower. The wind, water, insects, and animals transfer the pollen grains. They are called pollinating agents. Pollination is the act of transferring pollen from one flower to another. It is an important part of the life cycle of many plants, especially flowering plants such as flowers, fruits, nuts, seeds, and vegetables.
The stigma is made up of cells called stamens. Each stamen contains one or more ovules, each of which contains a single pollen grain. When the pollen reaches the female ovule, it attaches to it and begins the process of fertilization. This process takes place in a process called mitosis, in which the chromosomes of one chromosome are copied into the nucleus of another chromosome.
During this process, the two chromosomes are joined together to form a new cell, called a zygote. After the fertilized egg is implanted in the uterus (uterus), it begins to develop into a fetus (fetus), which then develops into an adult (adult).
What is pollination in simple sentence?
The flowers contain honey and attract flies and other small insects by the agency of which they are pollinated. Insects are not the only pollinators of plants. Bees, wasps, butterflies, moths, beetles, grasshoppers, ants, termites, etc. are also important. Insects pollinate plants in the same way as plants do. They feed on the pollen and nectar of the flowers.
For example, if a flower has a large number of bees in it, it is more likely to produce a good crop of honey than if it has only a few bees. Similarly, a plant with a lot of ants will be more productive than one with very few ants.
A plant that has lots of termite mounds will have a higher yield of sugarcane than a one-mound plant, because the ants are more efficient at extracting the sugar from the soil than the plants are.
What is pollination class5?
The transfer of pollen grains from anther to the stigma by various agencies called pollination. Pollination is the most common method of transferring pollen from a flower to a stigma. It is also the method used most frequently by honey bees. Pollen grains are deposited on the stamens of the flower and are then transferred by wind, water, or other means.
The pollen can then be used by bees to pollinate other plants. In the case of a pollinated plant, the plant will produce more pollen than it would have produced without the pollinator’s help. This is known as an increase in the number of flowers produced. However, this increase is not as great as it is for a plant that is self pollinating.
For example, if a honey bee pollinates one flower, it will only produce one pollen grain, but if the same flower is pollinized by two bees, one of them will be able to produce two grains and the other two will not be as effective as they would be if they were produced by one bee.
What is pollination Toppr?
Pollination is the transfer of pollen grains from the anther of one flower to the stigma of the same or another flower. It is believed to be the first process of sexual fertilization in plants. The male gamete is present in the anthers of the flowers. The pollen of a flower is carried by the wind from one plant to another. This process is known as pollination.
What is fertilization for Class 7th?
Fertilization is the process of fusion of pollen, the male gamete and egg, the female gamete. The formation of a zygote is a result of fertilization. One celled stage of an individual is called zygote and it divides to form two new cells. The fertilized egg develops into an embryo. The embryo is called a blastocyst.
Embryos are made up of two cells, a male cell and a female cell. When the embryo divides, it produces two sets of cells called gametes. Each set contains one set of chromosomes (chromosomes are the genetic material that make up a person’s body). The chromosomes in each set are called sex chromosomes. A person is either male or female.
What is pollination kid friendly definition?
The life cycle of plants is dependent on pollination. The plants can make seeds and reproduce if the insects, birds, bats, and the wind take pollen between flowering plants. Insects and birds pollinate plants in the same way as humans do, but they do it in a different way. Instead of taking pollen from flowers, they take it from the nectar of a plant.
This means that the insects are pollinating plants that have already been pollinated by other insects or birds. For example, if a flower has been visited by a hummingbird, it will be visited again and again by hummingbirds until it is completely covered by the humming bird’s wings. In this way, the plant is able to make new seeds.
Do all plants pollinate?
People can transfer pollen from one flower to another, but most plants are pollinated without help. Plants rely on animals or the wind to pollinate them. The answer depends on the type of plant you’re looking at. For example, if you look at a flower, you can tell if it’s a flowering plant or a non-flowering plant. On the other hand, plants that are not flowering will not release any pollen.
What is a flower Class 6?
Flowers are the colourful and beautiful part of the plant that are of various shapes, sizes, and colours. They are a part of the plant’s reproductive system. Flowering time is from the end of May to the beginning of June, depending on the type of flower you are looking for and the weather conditions.
Flowering times vary from plant to plant and season to season, so it is best to check with your local nursery or garden centre to find out the exact flowering time for your particular flower.
