    For many cells, this passage of all materials in and out of the cell must occur through the cell wall. Cells may grow larger as they receive food and oxygen. The larger the cell grows, however, the more nutrients it must stay healthy. Beyond a particular cell size, the cell wall cannot absorb nutrients quickly enough.
