Gas exchange

Diffusion

Detailed explanation-1: -Diffusion is the process of a substance spreading out to evenly fill its container or environment. In a solution, a concentrated solute diffuses to spread evenly in its solvent. In air, gas molecules diffuse to mix thoroughly. Substances diffuse from areas of high concentration to low concentration.
Detailed explanation-2: -In the process of diffusion, a substance tends to move from an area of high concentration to an area of low concentration until its concentration becomes equal throughout a space.
Detailed explanation-3: -Passive Transport Molecules have a natural tendency to move and spread out evenly in any available space. This property is called diffusion. An example would be a drop of dye in a section of a beaker separated by a permeable membrane.
Detailed explanation-4: -Diffusion is the net movement of substances from an area of higher concentration to an area of lower concentration. This movement occurs as a result of the random and constant motion characteristic of all molecules, atoms, or ions (due to kinetic energy) and is independent from the motion of other molecules.
Detailed explanation-5: -The kinetic energy of the molecules results in random motion, causing diffusion. In simple diffusion, this process proceeds without the aid of a transport protein. it is the random motion of the molecules that causes them to move from an area of high concentration to an area with a lower concentration.
