1-In this process energy (ATP) doesn’t require
2-both are downhill movement
3-movement of molecules occurs from higher conc.to lower conc.
These are the similarities
Both osmosis and diffusion equalize the concentration of two solutions. Both diffusion and osmosis are passive transport processes, which means they do not require any input of extra energy to occur.
In diffusion the molecule moves from Higher conc. To lower which is same as in osmosis but “of water molecules” in osmosis and they both don’t require any energy for that
