This type of pollination is essential since about 80% of all flowering plants and 75% of plants used to produce staple crops require the support of animals to accomplish the pollination process. Entomophilic Flowers are mainly pollinated by insects. This method increases plant species genetic variety, which improves their capacity to adapt to environmental changes and withstand plant diseases. Advantage : 1)Pollen grains are high in nutrients, hence pollen tablets are commonly used as food supplements in the Western world. Self-fertilization can occur regardless, in any event, when the quantity of blooms/blossoms is/nearly nothing. In easy words, Cross-Pollination is pollination that occurs between two flowers of two different plants but of the same kind.

Pollinators or pollinating agents are agents that transfer pollen from one flower to another. Cross-pollination is 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. Disadvantages of cross pollination: It is not always certain as a pollinating agent is always required, and it may or may not be available at the suitable time. 2. Chances are high that desirable qualities may get eliminated and unwanted characteristics may get added due to recombination of genes. The seeds developed when germinated under favorable conditions grow into healthier plants. Animals, birds, wind, insects, water, and other biotic and abiotic agents must act as pollinators throughout the cross-pollination process. Why is Cross Pollination important? Cross-Pollination takes place with the help of pollinating agents like birds, winds, insects, etc. The ability of some plants to self-fertilize has its advantages, especially in areas where there aren't many pollinating insects. However, self- pollination results in weaker progeny Advantages of out-crossing: Variation can occurs, which can cause evolution. Pollination is an important part of the plant reproductive process, as it is the process by which pollen grains are transmitted from male plants to female plants. 3. Question 2. Cross-pollination could also increase the probability of unwanted genetic mutations in plant species. No transmission of dust happens from one bloom to another.
