- Pollination by Wind (Anemophily): The flowers pollinated by wind are mostly small in size and do not have any attractive colour, smell and nectar. The pollen grains are non-sticky, dry, light and powdery. Hence, they are easily carried by the wind.
E.g. Grass, Maize, Pine.
- Pollination by Water (Hydrophily): The flowers of water plants are not colourful and they have no nectar. Pollen grains of these plants have mucilaginous covering to protect them from getting wet. They float in water and reach the other plant.
E.g. Vallisneria, Hydrilla, Zosteria.
- Pollination by Insects (Entamophily): This is the most common type of pollination in plants like sunflower, ladies finger, brinjal and pumpkin. Some flowers are large in size and they have a sweet smell. Some of these flowers produce nectar. They attract insects like butterflies and honey bees.
