Answer #1

In science, the terms diffusion and osmosis are two kinds of movement that does not require energy. The substances involve moves from its field of higher concentration to a field of lower concentration. Both can also occur in living and non-living things where the movements are being regulated by the coagulation of the affected molecules.

The major difference between diffusion and osmosis is primarily based on the kind of matter that is being transported. In diffusion, it involves passive movement of any forms of chemical from one place to another; in osmosis, it mostly involves movement of water molecules from higher solute concentration to lower solute concentration. Water is the only substance that can go through the process of osmosis.

Aside from what is stated above, there are other factors that distinguish diffusion from osmosis which are enumerated below:

-Diffusion and osmosis differ in relation to the direction of movement that takes place. In diffusion, the molecules of the substance involve may disperse in any direction; in osmosis, the course of the water molecules follows only one path.

-Diffusion can take place even without the involvement of a membrane whereas osmosis only happens from one porous membrane to another.

-Diffusion is not limited to occur on liquids, gases can also diffuse. However, osmosis can only arise in fluid or liquid solutions.

-The speed of movement also differs between diffusion and osmosis wherein the latter disperses a lot slower than the former.

-Diffusion may break up molecules in long distances. On the other hand, osmosis breaks up molecules in short distances.

Taking these concepts all together, one can conclude that osmosis is a form of diffusion that is selective or more specialized in nature. Whatever the differences may be, both are essential part of every man’s daily living.
