Difference between Diffusion and Osmosis | Plants

The upcoming discussion will update you about the differences between Diffusion and Osmosis. Difference # Diffusion: 1. It is the movement of all types of substances from the area of their higher free energy to the area of their lower free energy. 2. Diffusion can operate in any medium. 3. Diffusion is applicable to all types of substances— solids, liquids [...]

Difference between Diffusion and Imbibition | Plant Physiology

The upcoming discussion will update you about the differences between Diffusion and Imbibition. Difference # Diffusion: 1. Diffusion is movement of substances from the region of their higher concentration to the region of lower concentration. 2. An adsorbent is absent. 3. All the substances present in the medium show diffusion. 4. There is little change in pressure. 5. Energy is [...]
