$(2)$ Diffusion and Imbibition
$(1)$ Osmotic Pressure and Osmotic Potential
$(2)$ Diffusion and Imbibition
(N/A) $(1)$ Osmotic Pressure vs Osmotic Potential:
$(2)$ Diffusion vs Imbibition:
| Osmotic Pressure | Osmotic Potential |
| $(1)$ It is the pressure required to prevent the net movement of water into a solution across a semi-permeable membrane. | $(1)$ It is the decrease in the water potential of a solution due to the presence of solute particles. |
| $(2)$ It is always a positive pressure. | $(2)$ It is always a negative value. |
$(2)$ Diffusion vs Imbibition:
| Diffusion | Imbibition |
| $(1)$ Movement of particles from a region of higher concentration to a region of lower concentration. | $(1)$ $A$ special type of diffusion where water is absorbed by solid colloids, causing them to increase in volume. |
| $(2)$ It is a random movement of molecules. | $(2)$ It is a specific process involving adsorption of water by hydrophilic substances. |
| $(3)$ It occurs in gases, liquids, and solids. | $(3)$ It occurs specifically in solid substances (imbibants). |
