Diffusion is important to cells because it helps maintain the balance of materials needed for survival, such as oxygen and water.
- Diffusion is a spontaneous phenomenon that does not require expenditure of ATP where the molecules move along their concentration gradient.
- Diffusion is the process by which the transfer of respiratory gases occurs between the alveolus and the blood through the alveolus-capillary membrane.
- In the particular case of H2O, diffusion is called osmosis, the passage of water through the membrane or osmosis always takes place spontaneously and very quickly.
- H2O will diffuse from the compartment with the lowest concentration of solutes to the compartment with the highest concentration of solutes in such a way as to balance the concentrations in both compartments.
Therefore, we can conclude that diffusion is important to cells because it helps maintain the balance of materials needed for survival, such as oxygen and water.
