concentration of water molecules inside and outside the cell

thickness of the cell membrane

rate of movement of insoluble molecules inside the cell

temperature

rate of molecular motion on either side of the cell membrane

Osmolarity is expressed in osmolar units whilst tonicity is expressed in mm Hg hydrostatic pressure

Osmolarity depends on the concentration of particles in solution while tonicity tells us the fate of a cell placed in a solution

Osmolarity and tonicity describe the movement of water in a beaker separated into two compartments by an impermeable membrane

Osmolarity and tonicity describe the movement of water in a beaker separated into two compartments by a totally permeable membrane

Two solutions which are iso-osmotic can never be isotonic to a cell

No net water movement

Net water movement out of the cell

Decrease in cell volume

Increase in cell volume

Cannot be determined without knowing the body's temperature

will experience a net movement of water into the cell from the surrounding environment

will experience a net movement of water out of the cell into the surrounding environment

has a lower concentration of solutes than the surrounding environment

will undergo crenation

will not experience any net movement of water with respect to the surrounding environment

hyperosmotic and isotonic.

iso-osmotic and isotonic.

iso-osmotic and hypotonic.

iso-osmotic and hypertonic.

hyperosmotic and hypertonic.

Water moves by osmosis to a region where solute concentration is lower

Osmolarity is expressed in Osmolar units

A solution with a lower concentration of particles than another is said to be hypo-osmotic to the second solution

Osmolarity depends on the concentration of all solute particles in the solution

When two solutions have the same concentration of particles they are said to be iso-osmotic to each other

hypo-osmotic

isosmotic

isotonic

hypertonic

hyper-osmotic
