How are osmosis and delusion alike?

Answer: Osmosis and diffusion are alike in a way that in both motion of molecules/water is from the high concentration to low concentration. Both processes don't needs energy. Explanation: Osmosis is the process of movement of water from high concentration of water to low concentration of water across the permeable membrane. Diffusion is the transport of materials from high concentration to low concentration. Concentration gradient means the Movement always from higher to lower concentration of materials. So in the osmosis and diffusion movement is always from high to low concentration.

Note:

In this question delusion is mistakenly written. It is diffusion. Because there is no connection between delusion and osmosis. Correct word here is diffusion.

Diffusion refers to the movement of a substance from a region of higher concentration to the region of lower concentration. Osmosis refers to the procedure by which the molecules of solvent seems to go through a semipermeable membrane from a region of less concentrated solution to a region of more concentrated solution.

Diffusion takes place in the presence or in the absence of membrane between the two regions of distinct concentration of molecules. On the other hand, osmosis only takes place through a semipermeable membrane, a membrane that inhibits various molecules or particles to freely pass between the two sides of the membrane, while permitting the molecules of water to pass through.
