Detailed explanation-1: -Cross-pollination is the process of applying pollen from one flower to the pistils of another flower. Pollination occurs in nature with the help of insects and wind. This process can also be done by hand to produce offspring with desired traits, such as colour or pest resistance.
Detailed explanation-2: -Cross-pollinating-the plant needs a vector (a pollinator or the wind) to get the pollen to another flower of the same species.
Detailed explanation-3: -Transfer of pollen grains from anthers of one flower to the stigma of a flower of another plant of the same species is called as allogamy. This transfer can occur through some external agents like wind, water, insects or birds. Thus, allogamy is cross pollination.
Detailed explanation-4: -Cross-pollination occurs when pollen from one plant fertilizes the ovules of another plant. Some plants cannot set viable seed without cross pollination, as is the case with broccoli and many apple cultivars.
Detailed explanation-5: -The transfer of pollen grains from the anther of one plant to the stigma of another different plant is called cross-pollination.
