Osmosis Vs Diffusion

Osmosis is a specific type of passive transport that refers to the movement of water molecules across a selectively permeable membrane. This process occurs when there is a concentration gradient, with water moving from an area of lower solute concentration to an area of higher solute concentration in order to equalize solute levels on both sides of the membrane. Osmosis is crucial for maintaining cell turgor, regulating internal environments, and facilitating various physiological processes in living organisms.

Diffusion is the process by which molecules spread from an area of higher concentration to an area of lower concentration, resulting in an even distribution of substances within a given space. This movement occurs due to the random motion of particles and does not require energy input, making it a form of passive transport. Diffusion is essential in several biological functions, such as gas exchange in the lungs and the distribution of nutrients and waste products within cells.
