mitosis

Question 1

interphase

Answer 1

just before cell division begins
cell prepares for cell division

Question 2

prophase

Answer 2

chromosomes made of two chromatids are visible
nucleolus shrinks and disappears
centrioles move to opposite sides of the cell
spindle fibres form
nuclear envelope breaks down

Question 3

metaphase

Answer 3

chromosomes line up along equator of the cell
each chromosome is still made up of two chromatids joined at the centromere

Question 4

anaphase

Answer 4

chromatids separate and move to opposite sides of the cell
chromatids reach opposite sides of cell
exact copies of chromosomes are at both sides of cell

Question 5

telophase

Answer 5

chromosomes lengthen as they unravel
the nuclear envelope froms around each group of chromosomes to make two nuclei
new nucleoli form in each nucleus
two identical nuclei formed

Question 6

cytokinesis

Answer 6

cell membrane develops down the middle of the cell to divide it into two
two identical cells are produced
