The procedure described above involved the use of model cells. Hydrogen ions from the
acid were able to travel freely to the centre of the agar jelly cubes.
The rate of movement of molecules from the plasma membrane towards the centre of
living cells is often greater than that seen in the procedure the student carried out even if
the cells are kept at the same temperature.
Suggest a reason for this observation.
