How do petals contribute to the reproductive process of flowering plants?
They are colorful structures that attract pollinators
What are the male parts of a flower called?
Stamens
What is the function of the anther in a flower?
It produces pollen grains
What role does the stigma play in the fertilization process?
It is the sticky top part that receives pollen
What is the function of the style in a flower?
It is the tube connecting the stigma to the ovary
What does the ovary of a flower contain?
Ovules (potential seeds)
What is pollination?
It is the transfer of pollen grains from the anther to the stigma
What is the first step in the fertilization process of flowering plants?
Pollen tube growth
What is double fertilization in flowering plants?
It involves one sperm cell fertilizing the egg cell to form the zygote and another sperm cell fusing with two polar nuclei to form the endosperm
What does the zygote develop into?
The embryo
What is the role of the endosperm in seed development?
It provides nutrition for the developing embryo
What happens to the ovule after fertilization?
It develops into a seed
What is the seed coat and how is it formed?
The seed coat is formed from the ovule's integuments and protects the embryo and endosperm inside
What occurs during the maturation of a seed?
The seed dehydrates and enters a dormant state
How many cotyledons do monocots have?
One cotyledon
How many cotyledons do dicots have?
Two cotyledons
What are cotyledons in a seed?
Seed leaf(s) that store or absorb food
What will the embryonic stem (plumule) develop into?
The shoot system
What will the embryonic root (radicle) develop into?
The plant's root system
Female Reproductive organ
Is called the carpel and consists on the stigma, style and ovary
The embryo sac produces
The egg cell and two polar nuclei
The Ovule, Where is it?
The ovule is in the ovary and is part of the female reproductive organ called the carpel
What is inside the ovule
The Mother cell which is diploid
Nucellus
This is what most of the ovule is made up of, it provides nutrients to the developing embryo sac
The walls of the ovule are called the...
Integuments
What process does the Diploid mothercell undergo first?
The diploid mothercell undergoes meiosis to produce four haploid cells. Out of the cells produced three die off leaving only one.
After the mothercell undergoes meiosis and produces 4 haploid cells, only one cell remains because the other ones die off. What is the name of this one remaining haploid cell?
