Limits to Cell Size
... Limits to Cell Size Background Cells are the basic units of life. When cells become damaged, or simply grow too old, and need to be replaced, they undergo division: mitosis and cytokinesis. Also, when an organism grows in size, it’s due to the replication and reproduction of cells. Large organisms a ...
