mitosis

Question 1

prophase

Answer 1

chromatin threads condense and becomes visible as pairs of chromatids, the centrioles move to opposite ends of the cell, spindle fibres form

Question 2

metaphase

Answer 2

chromatids pairs move to the centre of the cell and line up along the equator of the cell, the centromere of each pair is attached to the spindle fibre

Question 3

anaphase

Answer 3

spindle fibres contract, splitting the centromere and pulling sister chromatids to opposite ends of the cell, the former chromatid is called chromosomes

Question 4

telophase

Answer 4

two sets of chromosomes densely packed together at either end of cell, a new nuclear membrane forms producing two identical nuclei,

Question 5

cytokinesis

Answer 5

the cytoplasm divides and the organelles evenly distribute themselves before separating into two daughter cells

Question 6

cytokinesis in animal cell

Answer 6

cleavage furrows develop, pinches plasma membrane

Question 7

cytokinesis in plant cells

Answer 7

cell plate forms at the equator
