Increased cell EFFECTS OF MUTATIONS division, possibly leading to cancer, can result if the cell cycle is overstimulated, as in (a), or not Protein Protein absent inhibited when it normally would be, overexpressed as in (b). Cells are complex and their components perform various functions in an organism. Cell Division<br />. Cell division is the process by which a parent cell divides and gives rise to two or more daughter cells. 10.1 CELL CYCLE Cell division is a very important process in all living organisms. The process of cytokinesis differs in animal and plant cells. • Define cell cycle: the cell cycle is the sequence of growth and division of a cell.
