In plant cells hypertonic medium
there loss of water the exterior, SF
0 (the vacuolar is high
because is concentrated) and = 0
(there no distension of cell wall
since cellular volume is ) so
DPD = . These cells are
plasmolysed cells, situation
by the retraction the
cell membrane detach from the
wall.

In plant under isotonic medium
is no increase the internal
water , SF > 0 TP = 0 (
the cell wall not distended). The
membrane slightly touches cell wall
and this situation the is called a
cell.

In plant under hypotonic medium
is tendency of to enter, SF
TP (since the pressure is
totally by the distension
the cell wall) DPD = 0. cell that
has itself to this is
called a cell
