How does the egg of a flower become fertilized?
as soon as the pollen reaches the stigma
after the pollen grain descends down the style
when the pollen tube grows into the ovule
when the seed germinates

When the pollen tube grows into the ovule

Explanation:

Simmilar to animals, fertilization occurs when the egg (ovule) and the sperm join together to produce a new individual. In flowers, when the pollen tube grows into the ovlue is when pollen and ovule join together and fertilization occurs. A new seed is the produced, ready to produce a new individual.

humans can cause extinction of a species through overharvesting, pollution, habitat destruction, introduction of invasive species (such as new predators and food competitors), overhunting, and other influences. explosive, unsustainable human population growth is an essential cause of the extinction crisis.
