1. Why can a cell not grow indefinitely larger?

  • As the cell size increase, the Surface Area: Volume ratio falls, So less of the cytoplasm has access to the cell surface so crucial substances are transferred less quickly.
  • As the cell size increases, the Sufrace Area: Volume ratio fall,s so more of the cytoplasm has access to the cell surface .
  • As the Surface Area; Volume ratio rises " "
