| Diffusion | Osmosis |
| This substance moves from the region of higher concentration to the region of lower concentration. |
In this water and substances in solution move from the region of high concentration to the region of low concentration. |
| Movement does not occur against the concentration gradient. |
Movement occurs against the concentration gradient in case of solute. |
| Semipermeable membrane is not required because transportation takes place through intercellular space |
It takes place through a semipermeable membrane because a semipermeable membrane only allows a solute particle to pass through it. |
Differentiate between Apoplast and Symplast pathways of movement of water in plants
Differentiate between Osmotic Pressure and Osmotic Potential
Differentiate between Transpiration and Evaporation
