Flowers also have a female part called the pistil. ... Seeds are made at the base of the pistil, in the ovule. To be pollinated, pollen must be moved from a stamen to the stigma. When pollen from a plant's stamen is transferred to that same plant's stigma, it is called self-pollination.

insects
Pollinator Insects. ... Many flowers produce nectar, a sugary liquid that many insects eat. When an insectlands on a flower to feed, pollen grains stick to its body.

Answer 2

pollination is the process of transfer of pollen grains from the anthers of one flower to the stigma of another flower or the same flower.
pollination occurs because of the agents of pollination like wind water insects animals etc.
insects help in cross pollination since the pollen grains are sticky or spiny and they stick to the body of the insect and drop off when the insect reaches the stigma
