1 Pollination
Different ways of pollination can include wind, water, birds, insects, butterflies, bats, and other animals that visit flowers. We call animals or insects that transfer pollen from plant to plant “pollinators”.
-
-
Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma.
-
Pollination is an essential part of plant reproduction. Pollen from a flower's anthers rubs or drops onto a pollinator. The pollinator then take this pollen to another flower, where the pollen sticks to the stigma. The pollen on the stigma then goes down the style and into the ovary.
-
It is an essential ecological survival function. Without pollinators, the human race and all of earth's terrestrial ecosystems would not survive.
-
Fertilization is a process of sexual reproduction, which occurs after pollination and germination.
-
From the anther the pollen grains are first deposited on the pistil's surface, the stigma. There they germinate and form pollen tubes, which grow downward through the style toward the ovules.
-
The beginning of the growth of a seed into a seedling is known as germination. All seeds need water, oxygen and the right temperature to germinate.
-
When a seed is exposed to the proper conditions, water and oxygen are taken in through the seed coat. Then the seed coat breaks open and a root emerges first, followed by the shoot that contains the leaves and stem.

-
Because plants cannot walk around and take their seeds to other places, they have developed other methods to disperse (move) their seeds. The most common methods are wind, water, animals, explosion.
