- A pollination flower transfers pollen grain from the anther to a stigma of a plant.
- A pollen is a small structure that contains male nuclei.
- Transfer in an insects pollinated plant is taken place by insects.
- Its necessary for this plant to attract insects.
- If pollen goes from one plant to another this is called cross pollination.
