Gr.9 Cell division

What is the purpose of mitosis?

• To increase the surface area of a cell
• To allow cells to divide for growth, repair, and renewal
• For increasing genetic variation within a species
• To allow for DNA replication and protein synthesis

Put the following stages of the cell cycle in order: G2, S, G1, M. 

• G1, S, G2, M
• S, G1, G2, M
• G1, M, G2, S
• M, G1, S, G2

What is the longest stage of the cell cycle called?

• Cytokinesis
• M phase
• Interphase
• G1 Phase

What stage is this?

• Prophase
• Metaphase
• Anaphase
• Telophase

What stage is this?

• Prophase
• Metaphase
• Anaphase
• Telophase

the division of the cytoplasm is called

• mitosis
• interphase
• cytokinesis
  Cytokinesis
• somatic
  somatic

Put the following stages of mitosis in order: anaphase, prophase, metaphase, and telophase. 

• prophase, metaphase, telophase, anaphase
• prophase, anaphase, metaphase, telophase
• prophase, metaphase, anaphase, telophase
• prophase, telophase, metaphase, anaphase

The structure labeled A is a(n)_________ used to hold sister chromatids together.

• chromatid

• centriole

• centromere

• chromophere

What happens in prophase of mitosis?

• The chromosomes become visible; nucleus disappear; spindles form

• The chromosomes align in the middle of the cell

• The sister chromatids separate

• The chromosomes uncoil into chromatin; nucleus reappears; spindles disappear

In mitosis, the two resulting cells are

• different from the starting cell and identical to each other.
• different from the starting cell and different from each other.
• identical to the starting cell and different from each other.
• identical to the starting cell and identical to each other.
