Pollination

Transfer of pollen from anther to stigma.

Pollination methods

Pollen transfer to stigma is aided by insects or wind.

Fertilization

Pollen grain absorbs liquid from stigma, pollen tube grows down style, enters micropyle, and nucleus of pollen grain combines with nucleus of egg cell.

Insect-pollinated Flowers

Wind-pollinated Flowers

Produce large quantities of light pollen so that anthers and stigmas can project themselves out of the flower.
