-the pollen lands on the stigma
-the pollen tube grows into the ovary
-the egg is fertilized
-the seed forms after fertilization
-when the seed is ready, it is spreaded
-the seed lands in soil and begins to germinate, starting the process over
The structures involved and their functions are as follows:
Stamen: The pollen-producing reproductive organ of a flower, consisting of an anther and filament.
Filament: The stalk portion of the stamen.
Anther: The terminal pollen sac of a stamen, where pollen grains containing sperm-producing male gametophytes.
Carpel: The ovule-producing reproductive organ of a flower, consisting of the stigma, style, and ovary.
Stigma: The sticky part of a flower's carpel, which receives pollen grains.
Style: The stalk of a flower's carpel, with the ovary at the base and the stigma at the top.
Ovary: The portion of a carpel in which the egg-containing ovules develop.
Petals: A modified leaf of a flowering plant. The petals are colorful to attract insects.
Sepals: A modified leaf that helps enclose and protect a flower bud before it opens.
Pollen: The fertilizing element of flowering plants. (Yellowish grains/spores)
Ovule: A structure that develops within the ovary of a seed plant that contains the female gametophytes.
Double fertilization is when two sperms cells unite in the angiosperm with two cells in the female gametophyte to form the zygote and endosperm.
