Osmosis and Tonicity

The movement of water across membrane to an area of higher solute concentration i.e. up a concentration gradient.

The pressure exerted by a liquid on the walls of its container.

The hydrostatic pressure caused by the difference in solute concentration in solutions separated by a semi permeable membrane.

The osmotic pressure gradient between two solutions separated by a semipermeable membrane.

A solution with the same tonicity as the inside the cell; the concentration of solutes in both solutions is the same.

A solution with a higher solute concentration that in the cell, it has lower osmotic pressure than that in the cell and draws water away from the cell.

A hypotonic solution as higher osmotic pressure than that within the cell due to a lower concentration of solutes. It will cause a movement of water into the cell.
