Define osmolarity and tonicity. How are they similar? How are they different?
What will be an ideal response?
Osmolarity refers to the concentration of individual particles in solution. Tonicity refers to the behavior of a cell in a solution. They are similar in that both are related to particles in solution. They are different in that osmolarity depends only on the total concentration of particles in solution, whereas tonicity depends on nature of the particles (i.e., are they penetrating or nonpenetrating) as well as on the concentration of the different particles.
