In easy words, Cross-Pollination is Pollination that occurs between two flowers of two different plants but of the same kind. New varieties of plants and crops can be developed through cross pollination. which help pollen grains transfer from one flower(one plant) to another flower (another plant) of the same species. - It helps in the introduction of new genes into a sequence of species. Advantages of cross pollination: The offspring are healthier. So when the insects and other creatures draw close to blossoms the dust adheres to the body of bugs, insects, and other creatures. Cross pollination is when one plant pollinates a plant of another variety. In easy words, Cross-Pollination is pollination that occurs between two flowers of two different plants but of the same kind. Cross-Pollination refers to the method of fertilization where the sperm from the pollen (from the anther) of a plant is transferred to the stigma of the flower of another plant. Distance between two plants becomes a barrier for pollination to take place. This results in lot of wastage of pollen. The pollen grain begins transporting sperm cells from the grain to the ovary when the pollen tube has been fully formed. What is cross-pollination and why is it important? Cross-pollination means that plants are dependent on pollinators. Among various plants that can self-pollinate are various kinds of orchids, peas, sunflowers, and so forth. Low genetic diversity means that a population has a limited level of natural resistance to change. Typically, this pollination method requires the assistance of pollinators, such as animals, humans, or wind and water. Self-pollinating plants are those that engage in this process. Advantages of cross-pollination: - Genetics recombination- as the pollination occurs between flowers of two different plants this results in the origin of new varieties.
