To understand the plant water relations, we should know the following process-
“The movement of molecules or atoms or ions of materials from an area of higher concentration to an area of their lower concentration is called diffusion.
Diffusion rate → Gas > Liquid > Solid
Diffusion pressure:
“The diffused molecules or ions exert a pressure on the substance or medium in which diffusion take place, known as Diffusion pressure.”
2. Temperature: The rate of diffusion is directly proportional to the increase in temperature.
3. Density: The rate of diffusion is inversely proportional to the square root of the density of the gas.
