Pollination
-
-
Pollination is an essential part of plant reproduction. Pollen from a flower's anthers (the male part of the plant) rubs or drops onto a pollinator. The pollinator then take this pollen to another flower, where the pollen sticks to the stigma (the female part). The fertilized flower later yields fruit and seeds.
Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma.
It is an essential ecological survival function. Without pollinators, the human race and all of earth's terrestrial ecosystems would not survive.

Fertilisation
-
Fertilisation is the process of combining the male gamete, or sperm, with the female gamete, or ovum.
-
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. Fertilization occurs as a sperm cell in a pollen tube fuses with the egg cell of an ovule, resulting in a plant embryo.
Seed Dispersal
-
Seed dispersal is the movement, spread or transport of seeds away from the parent plant.
-
It is 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 and fire. Dandelion seeds float away in the wind.
Germination
-
-
-
Seed germination starts with imbibition, when the seed takes in water from the soil. This triggers root growth to allow the seed to get more water. Then, the shoots develop and grow towards the sun above ground. After the shoots reach the ground, leaves form, allowing the plant to harvest energy from the sun.
