Diffusion and osmosis are passive transfer processes, meaning they do not require an input of energy for either of them to move substances. During biological processes, these two processes have an important role because they are useful for transporting water or nutrients between cells.
Nonetheless, both have some significant differences. One thing that distinguishes it is that diffusion can occur in any mixture, whether two solutions cannot be separated by a semipermeable membrane, while osmosis specifically only passes through a semipermeable membrane.
Apart from that, do you know any other differences between the two? If not, take a look at the following review which will explain the difference between diffusion and osmosis.

The difference between diffusion and osmosis

Diffusion and osmosis are descriptions that explain the processes that take place in the system. In this system there are particles or molecules that move randomly. Both of these processes aim to achieve equilibrium.
Although there is an association with the movement of substances through the membrane in both processes, diffusion and osmosis have differences. These differences include:
1. Definition of diffusion and osmosis
The difference between diffusion and osmosis can be seen from their understanding. Launch after The following is the meaning of diffusion and osmosis.
Diffusion
Diffusion is the process of moving particles from an area with a higher concentration level to an area with a lower concentration level until they reach equilibrium. In addition, simple diffusion does not require energy. Transfer in the process of diffusion through the plasma membrane. Osmosis
Osmosis is a process of movement of solvent particles through a semipermeable membrane from a higher solute concentration to a lower solute concentration. This process does not require any energy. Therefore, osmosis can also be interpreted as a diffusion event that specifically can only occur in water.
2. Use of a semipermeable membrane
The difference between diffusion and osmosis can also be seen in the presence of a semipermeable membrane. Reported Diffen, semipermeable membrane as a very thin layer of material that allows small molecules, such as water, oxygen, carbon dioxide, glucose, ammonia, and others to pass through. However, larger molecules such as sucrose or proteins cannot pass through it.
Diffusion
Reported Biology Libre Textsdiffusion events do not require a semipermeable membrane. Osmosis
Reported Libra Texts, Osmosis events will occur if liquids are separated by a semipermeable membrane.

3. A substance that diffuses
Another difference between diffusion and osmosis is the type of substance that is diffusing or the substance that is dissolving. Launch ThoughtCo The following is the difference between diffusion and osmosis in terms of the substance that is diffusing.

Diffusion
In diffusion, the solvent and solute particles are able to move freely. They can be substances such as gases, liquids, or solutes in the solution. Osmosis
In osmosis, only the solvent (water) can move through a semipermeable membrane.
4. Diffusion cannot be stopped while osmosis can be stopped
Diffusion
According to Encyclopedia Britannica, The osmosis process can be stopped by increasing the osmotic pressure or by increasing the pressure in the solution by a certain amount. Meanwhile, osmotic flow can be reversed by manipulating its osmotic pressure. Osmosis
Unlike osmosis, the process of diffusion cannot do such a thing. Launch Encyclopedia Britannica, the diffusion process cannot be stopped and even the flow cannot be reversed.
5. Flow of movement
The flow of movement in diffusion and osmosis also has differences. Reported after The following is the flow of movement from both of them.
Diffusion
In diffusion, particles or molecules will move from an area of high concentration to an area of lower concentration until they reach equilibrium. Osmosis
Osmosis will occur when water moves through a semipermeable membrane starting from an area of high concentration to an area of low concentration until it reaches osmotic equilibrium.
