Similarities:
- Both osmosis and diffusion involve the movement of molecules across a semi-permeable membrane.
- Both processes occur due to a concentration gradient, moving from an area of higher concentration to lower concentration.
Differences:
- Osmosis specifically involves the movement of water molecules across a semi-permeable membrane, while diffusion involves the movement of any type of solute.
- Osmosis is the movement of water molecules to equalize the concentration of solutes on both sides of the membrane, whereas diffusion is the movement of solute molecules to reach equilibrium.

What is the hypothesis to be answered for the osmosis and diffusion lab?
The hypothesis for an osmosis and diffusion lab could be: "If a semipermeable membrane is placed between two solutions of different concentrations, then water will move from the side with lower solute concentration to the side with higher solute concentration, resulting in a net movement of water through the membrane."
What is difusion and osmosis?
Diffusion is the process by which molecules move from an area of high concentration to an area of low concentration. Osmosis is a specific type of diffusion where water molecules move across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.
Two difference between osmosis and diffusion?
Osmosis specifically refers to the movement of water molecules across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration, while diffusion refers to the movement of molecules from an area of higher concentration to an area of lower concentration. Osmosis involves the movement of only water molecules, while diffusion can involve any type of molecule.
Is water osmosis?
Water is NOT osmosis. Although, osmosis is a special term used for the diffusion of water (moves from area of high concentration to low concentration). Used to identify that it is water being diffused, commonly in biology.
How does differences in concentration affect the rate of osmosis?
Higher concentration differences between the two solutions will result in a faster rate of osmosis. This is because a greater concentration gradient across the membrane drives water molecules to move more rapidly from the side with lower concentration to the side with higher concentration.
