52. mitosis
During G 2 phase of the Cell Cycle, the cell continues to grow to prepare for cell division (mitosis).

53. mitosis
During M phase (mitosis) of the Cell Cycle, the cell divides to produce 2 identical daughter cells.

54. mitosis
Cell division (mitosis) must take place so that it doesn’t become too large.

55. mitosis
Cells that are too large will need too much nutrients, produce too much waste, & make too many demands on DNA.
