How is cross pollination carried out in nature?
A, B, or C?
Answers
OPTION B is the correct answer
Cross-pollination is carried out by bees and other pollinators, which is present in option B, as cross-pollination is a process in which pollen from the male reproductive organs of a plant (such as the stamen) is transferred to the female reproductive organs.
Cross-pollination is facilitated by various agents, including insects, birds, wind, and even water. These agents inadvertently carry pollen from one plant to another as they move between flowers or plants. Insect pollinators, such as bees, butterflies, and beetles, are the most common and efficient carriers of pollen in cross-pollination. They visit flowers to obtain nectar or pollen as a food source, and in the process, pollen grains get attached to their bodies and are transported to other flowers.
