Process of diffusion can be summarised easily as the movement of uncharged ions, atoms or molecules through a biological membrane depends upon the permeability of biological membrane. Depending upon the permeability, the membrane may be semi permeable or differentially permeable, selectively permeable and impermeable. Here, the membrane is impermeable to pigment betacynin. That is why, pigment betacynin is unable to colourise the water.
