Pollination is what it is. Pollination is a biological process in which the pollen grains are transferred from an anther (male part of a flower) to the stigma (female part of a flower). Self-pollination occurs when a pollen grain from one flower is transferred to another flower. This is the most common type of pollen transfer, but it is not the only type.

For example, pollen from a plant that is pollinated by another plant may be deposited on the leaves of the pollinating plant. Another way of transferring pollen between plants is through the use of nectar. Nectar is produced by insects that feed on flowers, and is used to fertilize the flowers of other plants.

Some insects, such as bees and wasps, are able to pollinate flowers that are not their own. These insects are known as pollinators. Pollinators can also transfer pollen to plants that they have not yet visited.

What is pollination class 7th?

The process by which a flower’s anther is transferred from one flower to another is called pollination. 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 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 can be found in the anthers of the flowers. The female gametes are deposited on the stamens. The pollen is carried by the wind from one plant to another.

When the pollen reaches the ground, it is broken up by wind and carried away by rain. This process is called pollination. In some species of plants, pollen can be carried to a greater distance than in others. For example, some plants can carry pollen as far as 50 feet (15 meters) away from their flowers, while others can only carry it a few feet away.

What is pollination class5?

The transfer of pollen grains from anther to the stigma by various agencies. Pollen grains are transferred from the apical end of the pollen grain to a stigma. The stigma is the part of a plant that contains the ovary and the pistil, and is located at the base of each flower.

It is also called the staminate or pistillate part, because it contains pistils that are arranged in a spiral, or spiral-like, pattern. Stems of many species of flowering plants, such as flowers, fruits, nuts, seeds, etc., are also known as ovaries.

What is pollination in biology class 9?

Pollination is the transfer of pollen grains from the anther to the stigma of the same or another flower. The male gametes are produced inside the anthers of androecium while the female gametes are produced in the ovules of other flowers. Pollen grains can be divided into two types: the asexual and the sexual.

Asexual pollen is produced when the pollen grain is not fertilized by a sperm cell. Sexual pollen, on the other hand, is formed when sperm cells are present in a flower and fertilize the flower’s ovule. In both cases, the gamete (male or female) is transferred from one flower to another.

What is pollination class 6th?

Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma. Plants have a goal of creating offspring for the next generation. Plants are able to produce offspring by pollination. Pollination occurs when a male plant releases pollen into the air, which is then picked up by a female plant and carried by her to her offspring.

The answer depends on the type of plant you are looking at. For example, if you look at a flowering plant, you will see that the flowers are covered with tiny hairs called stamens. When a pollen grain is released from one of these hairs, it is called a nectar grain. If you take a piece of paper and hold it between your thumb and forefinger, the paper will become sticky.

This is because the sticky paper is made up of tiny droplets of pollen. You can see this in the picture below. If you hold your hand out in front of you, your fingers will be sticky, but your palm will not be. However, when you touch your palms together, pollen will come out of them.

What is pollination Class 7 with diagram?

In cross pollination, pollen grains from the anther (of a flower or of a plant) reaches the stigma of a flower of a different plant of the same kind. The male flowers produced more pollens in order to reach the female flower, which may not be in its vicinity.

In the case of plants of different kinds, the pollen of one species may reach the flowers of another species, and vice versa. In this case, it is not necessary to pollinate the two plants, but only to transfer pollen from one plant to the other.
