Cell Division
This is the name of the cell formed when two gametes combine during fertilization.
zygote
Your body is made up of ....
Cells
Why do we need cell division?
For growth, repair, and reproduction
This is the stage of meiosis when sister chromatids separate.
Anaphase II
This is the number of chromosomes in daughter cells after mitosis if the parent cell had 46.
46
Before a cell can divide, the chromosomes must be ...
duplicated
Name a type of artifical asexual reproduction
Cutting, Grafting, Vegetative propagation, cloning....
The first phase of the cell cycle
Interphase
In this type of reproduction, a new organism grows from a small outgrowth on the parent.
Budding
This is the process where sperm and egg combine to form a new cell.
fertilization
What does ploidy mean?
Refers to the number of copies of chromosomes
1n, 2n, ...
This process transfers pollen from the male part of a flower to the female part.
Pollination
The four stages of mitosis (cell division)
Prophase Metaphase Anaphase Telophase
These are the reproductive cells that combine during fertilization.
Gametes
Meiosis produces this many daughter cells.
4
A population that reproduces only asexually may struggle if the environment suddenly changes because of this reason.
low genetic diversity
This is the main disadvantage of asexual reproduction in changing environments.
low genetic variation
Humans have 46 chromosomes in body cells. This is the number of chromosomes in human gametes.
23
During this stage of meiosis, homologous chromosomes line up in the middle of the cell.
meiosis I
This process during meiosis increases genetic variation by exchanging DNA between chromosomes.
