How does pollination occurs in insect pollinated flowers?

Many flowers produce nectar, a sugary liquid that many insects eat. When an insect lands on a flower to feed, pollen grains stick to its body. As the insect moves to another flower of the same species, these pollen grains are transferred to the flower’s stigma and pollination occurs. read more

Pollination is the transfer of pollen grains from the anther to the stigma of a flower. Insect pollinated flowers usually produce sweet nectar which the insects go to feed on. If it's a self pollinating flower, the pollen stock on insect is dropped on the stigma of the flower which results in fertilization. read more

Self pollination can occur in relatively common species, such as the dandelion, which can be pollinated by insects, or it can do the job itself. This ability is obviously useful to the flower when there are few insect (or animal) pollinators to assist in the process. read more
