The cells are in a zone where there is a huge focus contrast. For instance, oxygen particle focuses could be exceptionally high outside of the cell and extremely low inside.
Those oxygen particles are little to such an extent that they can cross the lipid bilayer and enter the cell.
This is a water explicit procedure. For the most part, cells are in a domain where there is one convergence of particles outside and one inside.
