2 Cell Size Surface Area (length x width x 6) Volume (length x width x height) Ratio of Surface Area to Volume Ratio of Surface Area to Volume in Cells Go to Section:

3 Cell Cycle The cell cycle represents recurring events that take place in the period of time from the beginning of one cell division to the beginning of the next. In addition to cell division, the cell cycle includes periods when the cell is growing and actively producing materials it needs for the next division. Go to Section:

Limits to Cell Growth Why do cells divide rather than continuing to grow indefinitely?  The larger a cell becomes, the more demands the cell places on.
