Finding the concentration of a Potato cell.
s an example of the net movement through a partially permeable membrane. The right side is the more dilute solution, which makes it the hypotonic solution. The left side is the less dilute solution, w ... less dilute solution, which makes it the hypertonic solution. Net movement occurs through the more dilute to the less dilute so it goes from left to right though the partially permeable membrane. As ...

OSMOSIS- WHAT IS IT AND HOW DOES IT OCCUR IN GENERAL
In the 1st option, if the medium surrounding has a higher water concentration than the cell (a very dilute solution) the cell will gain water by osmosis. Water molecules are free to pass across the ce ... to swell, the cell wall prevents it from bursting. Plant cells become 'turgid' when they are put in dilute solutions, which mean that it becomes swollen and hard. The pressure inside the cell rises, a ...
