Does pollination occur when pollen combines with an egg?
In cross-pollination, a pollinator (such as a bee or a butterfly) takes pollen from one plant to an entirely different plant. Then, when the pollen combines with the egg of the new plant, the seeds have DNA from different plants. In self-pollination, a plant's pollen is used to fertilize its own eggs. Thus, the seeds have the same DNA as the original plant.
What is a process in which pollen from one plant is used to pollinate the eggs in the flower of a different plant?
There are three common kinds of pollination: self pollination, wind pollination, and insect pollination. •Self pollination is when the pollen in the stamen (male part of the plant) drops into an ovule (egg) in the ovary of the stigma (female part) of the same plant. This is why it is called self pollination. • Wind pollination occurs in plants that are all-male (its flowers only containing stamen) and all-female (its flowers only containing the stigma)…
The agents of pollination include, animals, wind, water, and expulsion. They are necessary in the growth and reproduction of flowering and cone plants. Without these methods of travel pollen(male) could not reach the egg(femaile) of the flower and fertilization and reproduction could not occur in these plants.
Pollination brings together the gametes of a flower and it occurs when a pollen grain of the right kind lands on the stigma of the pistil. Each pollen forms a tube that grows down through the pistil and reaches the ovule in the ovary. One of the nuclei in the pollen tube unites with the egg nucleus in the ovule to form a zygote. The other sperm nucleus combines with another bigger nucleus in the…
