Self pollination, wind pollination, and insect pollination are the three ways that pollination occurs. Pollination is needed in order for plants to reproduce.
Pea flowers are self-pollinating. About two days before the flower even opens, the anthers at the top of the stamen, which are the male part, burst and release the pollen. This sticks onto the stigma and fertilizes the ovary - these are the female parts. In many flowering plants, the stigma will not accept pollen from the same plant and fertilization must occur through other means, such as insect pollination after the flower opens. For gardeners, self-pollination is an advantage as it means more than one type of pea can be grown close together, as cross-pollination will not occur.
The movement of pollen from a stamen to a pistil is called pollination. This can occur through wind, water, or by animal pollinators like bees, birds, or butterflies transferring the pollen between the reproductive organs of a flower. Once the pollen reaches the pistil, fertilization can occur, leading to the formation of seeds.
The transfer of pollen from the anther to the stigma is called pollination. This process is essential for fertilization and the production of seeds in plants. Pollination can occur through various means, such as wind, insects, birds, or other animals.
Pollen lands on the stigma, which is the sticky female reproductive part of the flower, during pollination. This interaction allows for fertilization and the formation of seeds.
One main difference is that gymnosperms typically rely on wind for pollination, while angiosperms often rely on animals like bees for pollination. Additionally, gymnosperms have exposed seeds, while angiosperms have seeds enclosed within a fruit. Finally, gymnosperms do not produce flowers, while angiosperms do.

pollination occurs because the bees go from plant to plant to collect pollen to store in their honey
If one event can occur in m ways, and for each of these a second event can occur in n ways, then the number of ways that the two evens can occur together is m x n. Can be extended to three or more events.
