mitosis and meiosis

Question 1

What is the result of mitosis

Answer 1

2 genetically identical diploid daughter cells which are used for growth and repair

Question 2

What is the result of meiosis

Answer 2

4 genetically non identical haploid daughter cells that go on to either develop into sperm or egg cells

Question 3

What happens during interphase

Answer 3

The cell grows and replicates its DNA and its sub cellular structures increase in size to prepare for mitosis

Question 4

What happens during prophase

Answer 4

The chromosomes condense, getting shorter and fatter.
The membrane around the nucleus breaks down and the chromosomes lie free in the cytoplasm

Question 5

What happens during metaphase

Answer 5

The chromosomes line up at the centre of the cell

Question 6

What happens during anaphase

Answer 6

Spindle fibres pull the chromosomes apart.
Then the chromatids are pulled to opposite ends of the cell.

Question 7

What happens during telophase

Answer 7

Membranes form around each of the sets of the chromosomes.
These become the nuclei of the two new cells- the nucleus has been divided

Question 8

What happens in cytokinesis

Answer 8

before telophase ends, The cytoplasm and cell membrane divide to form two separate cells.
