This is a picture of what mitosis phase?
Metaphase
The stage of the cell cycle where most of your cells in your body is actually dividing
Mitosis
Which one of the following statements are NOT true about meiosis.
4 cells are produced cells are diploid
cells produced are genetically different from the parent and each other
cells are diploid (the cells are haploid)
Which one of the following statements are NOT true about mitosis?
4 cells are produced cells are diploid
cells produced are genetically the same from the parent and each other
4 cells are produced (only 2 cells are produced)
reproduction that requires only 1 parent
reproduction that requires 2 parents
asexual - mitosis
sexual - meiosis
What phase of meiosis is this? (*remember to include 1 or 2 in your answer)
Anaphase 1
The special type of cell division that only occurs in the gonads.
meiosis
Compared to the parent cell daughter cells have ___________ the chromosomes
half the chromosomes
Compared to parent cells, daughter cells have the __________ number of chromosomes.
3 reasons cell division in humans is important.
(hint 2 are from mitosis, 1 is from meiosis)
mitosis - growth and repair
meiosis - sexual reproduction
What is happening here?
Cytokinesis
During this phase the chromosomes are now visible, the nuclear envelope breaks down, and spindle fibers form.
prophase
In ______________ the homologous chromosomes pair up forming _________________ and crossing-over occurs.
Prophase 1
tetrads
The stage when the sister chromatids are moving away from each other.
Anaphase
What is the benefit of this process?
cross-over
creates diversity
What phase of meiosis is this? (*remember to include 1 or 2 in your answer)
Anaphase 2
At the beginning of prophase the chromatin condense and become visible the are now called ___________
Chromosomes
In meiosis 1 ___________ are separtated
in meiosis 2 ___________ are separated
(hint: is it sister chromatids, diploid, homologous chromosomes, or haploid)
homologous chromosomes
sister chromatids
What is the acronym to remember the phases of mitosis AND what does it stand for?
PMAT - Prophase, metaphase, anaphase
What is the end product of mitosis?
What is the end product of meiosis?
2 cells (genetically) identical to each other and the parent cell
4 cells (genetically) different from each other and the parent cell
Daily double: Draw a tetrad showing crossing-over taking place.

What happens during G1, S, and G2?
G1 - cell grows and carries out normal functions
S - DNA replicates
G2 - organelles duplicate
Meiosis happen in the ____________ and creates __________ (vocab words)
gonads and gametes
Mitosis happens in _______________________ and creates ______________
Answers may vary:most cells in the body, somatic cells
Daily Douuble: The 2 chromosomes that are a matching pair in your chromosomes are called _____________. You inherited one from your mom and one from your dad
Gametes contain only 1 set of chromosomes and are said to be ___________
Homologous (chromosomes)
haploid
