Cell Division- Mitosis

Question 1

What does a body cell need to do when it divides?

Answer 1

When a body cell divides it needs to make new cells identical to the original cell-with the same number of chromosomes

Question 2

When a body cell divides and needs to make new cells are identical to the original cell. What is this cell division called?

Answer 2

This type of cell division is called mitosis

Question 3

What is Mitosis

Answer 3

Mitosis is when a cell reproduces itself by Splitting to form two identical offspring

Question 4

What happens after a cell gets a signal to divide?

Answer 4

The chromosomes line up at the centre of the cell and cell fibres pull them apart

Question 5

Does asexual reproduction use mitosis?

Answer 5

Yes

Question 6

What does Mitosis do?

Answer 6

Mitosis makes new cells for growth and repair

Question 7

What type of cell division is involved in the regeneration of body parts?

Answer 7

Mitosis

Question 8

Describe how a cell divides to form gametes (3)

Answer 8

Before the cell starts to divide the DNA is duplicated. The cell then divides twice during which the chromosomes line up in pairs and are pulled apart. Four gametes are produced each with a single set of chromosomes

Question 9

State three ways in which mitosis is different from meiosis

Answer 9

i) Mitosis involves one division instead of two
ii) Mitosis keeps the chromosomes constant rather than halving the chromosome number
iii) Mitosis produces genetically identical cells rather than producing genetically different cells
iiii) Mitosis produces body cells rather than gametes
