Question

1. explain how osmosis differs from diffusion.

Explanation:

Osmosis is the movement of water molecules across a semi - permeable membrane from an area of lower solute concentration to an area of higher solute concentration. Diffusion is the movement of any molecules (not just water) from an area of higher concentration to an area of lower concentration. Osmosis specifically involves water and a semi - permeable membrane, while diffusion can involve various substances and does not necessarily require a semi - permeable membrane.

Answer:

Osmosis is the movement of water across a semi - permeable membrane from low to high solute concentration. Diffusion is movement of any molecules from high to low concentration. Osmosis is water - specific and needs a semi - permeable membrane; diffusion is more general.
