what do you call the phenomenon When you have a different concentration of materials on the inside and outside of the cell

Answers

Answer: Osmosis

Explanation:

Osmosis can be defined as the phenomenon in which there is a difference in the concentration of materials on the different sides of the cell.

The concentration inside the cell is different and the concentration outside is different.

The membrane in between is the semipermeable membrane which allows the movement of certain molecules.

The movement of solvent takes place from a region of their higher concentration to the area of lower concentration via semipermeable membrane.

Answer: Osmosis

Definition: A process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane.
