When do cells divide?
When neighboring cells die, opening up space in a tissue to be occupied by new cells
When they snugly contact neighboring cells or when nutrients or growth factors are withdrawn
When they have replicated their DNA, so they can give each daughter cell a duplicate set of genes
When they grow large enough to have enough cytoplasm to distribute to their two daughter cells
