Cell Division: Mitosis

Question 1

What is Mitosis?

Answer 1

A type of cell division in which a diploid (contains two complete set of chromosomes) copies itself and finally divides itself into two identical diploid daughter cells

Question 2

1. Interphase

Answer 2

The longest stage of Mitosis:

• When the cell grows and increases the number of sub-cellular structures.
• DNA replicates to create two copies of each chromosome.

Question 3

2. Prophase

Answer 3

• DNA in chromosome and their copies condense

Question 4

3. Metaphase

Answer 4

• Chromosomes line up in the middle

Question 5

4. Anaphase

Answer 5

• Chromosomes pulled apart to different ends of the cell

Question 6

5. Telophase

Answer 6

• New membranes form around the chromosome at each end of the cell.

Question 7

6. Cytokinesis

Answer 7

• Division of two daughter cells

Question 8

When does a cell need mitosis?

Answer 8

• When the organism grows
• When the organism becomes damaged and needs to be repaired.
• An organism like bacteria needs mitosis to produce asexually.
