The movement of molecules or ions from the region of higher concentration to the region of lower concentration, until the molecules are evenly distributed throughout the available space is known as diffusion.
Importance of diffusion in living beings:
- It plays an important role in gaseous exchange between the cells as well as the cell and its external environment.
- The movement of ions that generates the electrical nerve impulses occurs through diffusion.
- It helps in the absorption and distribution of water in plants.
- It helps in CO2 intake and O2 output in photosynthesis and CO2 output and O2 intake in respiration.
- It is involved in the transpiration of water vapour.
- It helps in the absorption of ions during passive salt uptake.
- It is an effective means of transport of substances over very short distance and helps in translocation of materials.
