The osmotic pressure is the hydrostatic pressure produced by a solution in a volume divided by a semipermeable membrane due to the difference in solute concentrations.
A hypotonic solution, also called hypotonic, is a solution in which the solvent (such as a diluted plasma) has a lower concentration of solute (salts, etc.) than that in the internal cell medium (or cytoplasm). In hypotonic conditions the cell will increase its volume, since, in an attempt to restore the osmotic equilibrium on both sides of the cell membrane, the solvent will diffuse into the cell. biology
In biology, a hypotonic solution is one that has a lower concentration of solute in the external environment in relation to the internal environment of the cell, that is, inside the cell there is a greater amount of salt than that which is found in the environment in which it lives, a cell immersed in a solution with a lower concentration of dissolved materials is in a hypotonic environment; the concentration of water is higher (because of having so few dissolved materials) outside the cell than inside. Under these conditions, the water diffuses to the cell, that is, osmosis of liquid is produced inside the cell.
A cell in a hypotonic environment swells with water and can explode; When this happens in the red blood cells, it is called hemolysis. Organisms that live on stream and lake soils inhabit modified rainwater, which is a hypotonic environment. The animal cells suffer the phenomenon of cytolysis, which leads to the destruction of the cell, due to the passage of water inside it. On the other hand, the turgor pressure phenomenon occurs in plant cells: when water enters, the cell swells but is not destroyed due to the high resistance of the cell wall. Notes
