|
in hypertonic solution the cell will:
|
expel water and shrivel up
|
|
|
when water enters the cell then this means it is :
a) hypotonic b) hypertonic c) isotonic |
a) hypotonic
|
|
|
the definition of isotonic is:
|
an isotonic solution is when two solutions have the same osmotic pressure
|
|
|
define HYPERTONIC
|
the concentrations of a solution is higher outside of the cell, the cell shrivels. (water diffuses)
|
|
|
define HYPOTONIC
|
the concentration of a solution OUTSIDE the cell is lower so water diffuses into the cell
|
