Similarities

  • they both move from a high to low concentraction across a concentration gradient.
  • they both require energy.
  • they both transport water.

Differences

  • diffusion moves substances.
  • osmosis moves water.
  • diffusion also transports carbon dioxide, oxygen, water, food substances and wastes.
  • osmosis only transports water.

Overall comparison

diffusion and osmosis are similar in the fact that they transport substances and water from a high to low concentration across a concentration gradient and they require no energy whilst doing so. But whereas diffusion also transports many other substances, osmosis only carries water.
