Which of the following is NOT a reason for why cells divide?
- Cells divide to make an organism bigger.
- Cells divide to repair damaged or dead cells.
- Cells divide in order to make an organism smaller.
- Cells divide in order to reproduce.
Cells divide in order to make an organism smaller.

A cell spends most of its life:
- Growing and performing its function(s)
- Replicating its DNA
- In mitosis
- In cytokinesis
Growing and performing its function(s)
100
During which phase does a cell replicate its DNA?
Interphase
100
What is a chromosome?
- The totality of genetic information in a cell
- An exchange of genetic traits
- The region where microtubules are formed
- The region where two sister chromatids attach
- The totality of genetic information in a cell
100
Cell division by mitosis produces:
- Two cells identical to each other but not to the parent cell
- Two cells identical to each other and to the parent cell
- Two cells with half the amount of DNA as the parent cell
- Two cells with twice the amount of DNA as the parent cell
Two cells identical to each other and to the parent cell

Most unicellular organisms use cell division (specifically mitosis) to:
- Make identical copies of themselves
- Create new and unusual unicellular organisms
- Increase variation in their species
- Become a multicellular organism
- Make identical copies of themselves
200
During which stage of mitosis do the chromosomes line up down the middle of the cell?
Metaphase
200
- Which phase of mitosis is shown in the diagram below?
Anaphase
200
Which statement below correctly describes meiosis?
- Meiosis is important to producing body cells that are diploid
- During meiosis, a cell undergoes two cell divisions and produces 4 daughter cells
- During meiosis, a parent cell produces daughter cells with twice the amount of DNA as a gamete
- All of the above
During meiosis, a cell undergoes two cell divisions and produces 4 daughter cells
200
Meiosis occurs in:
- Asexually reproducing organisms only
- Sexually reproducing organisms only
- Asexually or sexually reproducing organism
- Organisms that will not reproduce
Sexually reproducing organisms only

Meiosis is important to the production of...
Gamates
300
During which stage of meiosis do chromosome line up in pair down the center of the cell?
Metaphase I
300
How is mitosis and meiosis similar? (3)
- Both are types of cell division
- Both are important to sexual reproduction
- The daughter cells of both mitosis and meiosis inherit genetic information from a parent cell
300
- Which processes are important to increasing genetic variation in asexually reproducing organisms?
- Independent assortment
- Crossing over
- Both options
- Neither options
Neither options
300
How are the cells formed by meiosis different from the cells formed by mitosis?
Mitosis - 2 diploid daughter cells
Meiosis - 4 haploid daughter cells
400
What is the difference between mitosis and cytokinesis?
Mitosis - PMAT
Cytokinesis - Splitting of the cell
400
Compare and contrast prophase in mitosis and prophase I in meiosis.
Condensing of chromosomes.
Meiosis - homologous pairing and crossing over
400
What is the difference between metaphase I and metaphase II?
MI - chromosomes aligned in pairs
MII - single file line
400
Explain what happens during interphase. What would happen if interphase did not occur?
DNA replication, Cell growth and functions.
Cell division would not occur.
