| Osmotic pressure is the pressure exerted by a solution when it is in equilibrium with a second solution. | Hydrostatic pressure is the pressure exerted by a fluid due to its weight. |
| Osmotic pressure is determined by the concentration of the solute. | Hydrostatic pressure is determined by the height of the fluid column. |
| Osmotic pressure is affected by temperature. | Hydrostatic pressure is not affected by temperature. |
| Osmotic pressure is important in biological systems, as it affects the movement of water and solutes across cell membranes. | Hydrostatic pressure is important in biological systems, as it affects the flow of fluids in the body. |
