penatration.
This is called diffusion. Substances move randomly, from an area of high concentration to an area of low concentration. Osmosis is a specific type of diffusion that only involves the random movement of water.
In diffusion, substances flow with a concentration gradient, meaning that they flow from areas of high concentration to areas of lower concentration. Flowing against a concentration gradient would be going from an area of low concentration to an area of higher concentration, but this only occurs in active transport.
This is called a concentration gradient, which represents the difference in concentration of a substance between two locations. The substance will naturally move down the concentration gradient from areas of higher concentration to lower concentration through processes like diffusion or active transport.
Diffusion is the movement of a substance from an area of high concentration to an area of low concentration, driven by the random motion of molecules. It is a passive process that does not require energy input.
The movement of a substance from an area of high concentration to an area of low concentration is known as diffusion. This process occurs due to the random motion of particles, leading to a net movement of particles down their concentration gradient. Diffusion is driven by the principle of entropy, seeking to achieve a state of equilibrium where the concentration of the substance is uniform throughout the system.

Diffusion occurs when there is a concentration gradient i.e. a substance moves from higher to lower concentration.

For simple diffusion to occur, a concentration gradient must exist where a substance moves from an area of higher concentration to an area of lower concentration. Additionally, the cell membrane must be permeable to the substance diffusing, allowing it to pass through freely.
