Cells divide at different rates
Rates of cell division vary widely and are linked to the body’s need. The length of gap 1
varies most widely among cell types. Some cells, such as neurons, enter a stage called
G0, where cells are unlikely to divide again.
Cell size is limited
If cells were too small, they could not contain all the organelles and molecules necessary for
life. If cells were too large, they could not move enough materials across the membrane
surface. To maintain a suitable size, cell growth and division must be coordinated.
The smallest cube should be circled.
