The movement of water across membrane to an area of higher solute concentration i.e. up a concentration gradient.
What is hydrostatic pressure?
The pressure exerted by a liquid on the walls of its container.
What is osmotic pressure?
The hydrostatic pressure caused by the difference in solute concentration in solutions separated by a semi permeable membrane.
What does tonicity refer?
The osmotic pressure gradient between two solutions separated by a semipermeable membrane.
What is an isotonic solution?
A solution with the same tonicity as the inside the cell; the concentration of solutes in both solutions is the same.
What is a hypertonic solution?
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.
What is a hypotonic solution?
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.
