Detailed explanation-1: -cross-pollination, also called heterogamy, type of pollination in which sperm-laden pollen grains are transferred from the cones or flowers of one plant to egg-bearing cones or flowers of another.

Detailed explanation-2: -Transfer pollen grains from the anther to the stigma of a different flower. This process can take place in the same flower or a different flower of the same plant. This process can take place between two flowers present on different plants.

Detailed explanation-3: -Examples of plants that use insects for cross-pollination include apples, plums, pears, raspberries, blackberries, blackcurrants, strawberries, runner beans, pumpkins, daffodils, tulips, heather, lavender, and most flowering plants.

Detailed explanation-4: -Cross-pollination occurs between the flowers of the same species of plants is known as xenogamy. Pollen grains are transferred from the anther of one plant’s flower to the stigma of another plant’s flower in xenogamy.
