Limits to Cell Growth
__________ of Surface Area to Volume  
As the ____________ of a cell ___________, its volume increases ________ than the surface area.
The __________ in the cell’s ratio of surface area to volume makes it more ____________ for the cell to move needed materials in and waste products out quickly enough for the cell to _____________.

Limits to Cell Growth
As the length of a cell increases, its volume increases faster than its surface area. The resulting decrease in the cell’s ratio of surface area to volume makes it more difficult for the cell to move needed materials in and waste products out.
