Investigations into biophysical regulation mechanisms of physiological water exchange of the Nitella translucens cells with the surroundings

In the present paper, we have presented a theoretical discussion of specific biophysical mechanisms pertaining to the regulation (by means of internal factors) of physiological water exchange with the water medium by the cells of the Nitella translucens. The investigation has demonstrated that these cells have a capacity for water exchange regulation through changes in the values of transport parameters of the cell membrane (i.e. the filtration coefficient L_p and the reflection coefficient σ), as well as changes in the concentration C_si (inside the cells) of the osmotically active solute.
