Flower self pollination
WebSelf-pollination, or more exactly almost full self-pollination, is the principle mating system found in grain crops and in many vegetables.

WebIn cross-pollination, pollen grains are transferred from one plant to another by flies, bees, and animals when they suck nectar and sit on another flower, and dispersed them onto it. While in self-pollination, pollen sheds onto its own directly into the stigma.

Self-pollination is a form of pollination in which pollen from the same plant arrives at the stigma of a flower (in flowering plants) or at the ovule (in gymnosperms). There are two types of self-pollination: in autogamy, pollen is transferred to the stigma of the same flower; in geitonogamy, … See more Few plants self-pollinate without the aid of pollen vectors (such as wind or insects).

WebPollination is a very important part of the angiosperm life cycle. It can happen two different ways. Self-pollination is when pollen moves from one flower to another on the same plant, or even from an anther to a stigma on the same flower. Self-pollination has the advantage of occurring easily – plants need little or no outside help to move ...
WebPollen is made by the male organs of a plant (stamens in flowers) and contains genetic information needed for plant reproduction. Pollen may be transferred to female organs on the same plant (self-pollination) or another plant of the same species (cross-pollination).
