Chapter 9: Cellular Reproduction CELLULAR GROWTH -As the cell grows, its volume increases much more rapidly than the surface area. -The cell might have difficulty supplying nutrients and expelling enough waste products. TRANSPORT OF SUBSTANCES -Substances move by diffusion or by motor proteins. -Diffusion over large distances is slow and inefficient. -Small cells maintain more efficient transport systems. CELLULAR COMMUNICATIONS -The need for signling proteins to move throughout the cell also limits cell size. -Cell size affects the ability of the cell to communicate instructions for cellular functions. THE CELL CYCLE -Cell division prevents the cell from becoming too large -It also is the way the cell reproduces so that you grow and heal certain injuries
