Wind pollination is a common form of abiotic pollination .It requires light and non-sticky pollen grains that can be carried by wind currents.A familiar example of wind pollination is observed in corn, where the tassels represent the stigma and style that wave in the wind to trap pollen grains. Grasses are a common example of plants that rely on wind pollination.

Pollination by water is quite rare in flowering plants and is limited to about 30 genera, mostly monocotyledons.  Some examples of water pollinated plants are Vallisneria and Hydrilla which grow in fresh water and several marine sea-grasses such as Zostera.

Insect pollination, or entomophily, involves the transfer of pollen grains by insects such as bees, butterflies. Flowers that rely on insect pollinators often have bright colors, attractive scents, and nectar rewards to attract the insects.

Certain plant species offer floral rewards by providing secure locations for egg-laying. One example is the tallest flower of Amorphophallus, which can reach a height of approximately 6 feet. Similarly, a comparable relationship can be observed between a particular moth species and the Yucca plant. Flowers provide a protected environment for their eggs, ensuring the survival of their offspring.
