mitosis

Question 1

what is mitosis?

Answer 1

a type of nuclear division carried out by diploid body cells

Question 2

what happens to the cell nucleus?

Answer 2

it divides into two

Question 3

what are the daughter cells like?

Answer 3

genetically identical to eachother

Question 4

what number of chromosomes do the daughter cells have?

Answer 4

diploid- 46

Question 5

what is mitosis required for?

Answer 5

growth
repair of damaged tissue
asexual reproduction

Question 6

what happens before mitosis must occur?

Answer 6

these chromosomes must be replicated to double the amount of genetic material in the nucleus

Question 7

what happens to the chromosomes after they are replicated?

Answer 7

they now appear as X shapes

Question 8

what happens to the X shaped chromosomes?

Answer 8

they are then pulled apart- one half of each being pulled to either end of the cell

Question 9

what happens once the chromosomes are pulled to separate ends of the cell?

Answer 9

the cytoplasm and membrane split- resulting in two genetically identical diploid daughter cells which contain the same chromosome number as the parent cell
