Comparing diffusion, osmosis and active transport.
Diffusion and osmosis both refer to the movement of particles across a semipermeable membrane, such as the phospholipid bilayer of the cell membrane.
Diffusion, Osmosis, Active Transport There are two ways in which substances can enter or leave a cell: 1) Passive a) Simple Diffusion b) Facilitated Diffusion c) Osmosis (water only) 2) Active a) Molecules b) Particles Diffusion Diffusion is the net passive movement of particles (atoms, ions or molecules) from a region in which they are in higher concentration to regions of lower concentration.

Diffusion and osmosis are both types of passive transport. Thus, both of them occur in a downhill manner and without energy expenditure. The difference is the diffusing molecules or particles. In diffusion, the diffusing particles are the solutes of a solution. In osmosis, the diffusing particles are the solvent of the solution, i.e. water molecules. In osmosis, water molecules diffuse from an.
Difference Between Diffusion and Osmosis. February 9, 2011 Posted by Olivia. Diffusion vs Osmosis. Diffusion and Osmosis are physical processes that are often confused with one another and people find it difficult to differentiate between the two. These are processes that are found in nature and are related with movement of atoms and molecules from areas of higher concentration to areas of.
