    May 05, 2020 Chloride: An Essential Nutrient. Chloride is rarely thought of as an essential nutrient. But it is! Chloride’s function in the plant is primarily for osmoregulation, (the maintenance of constant osmotic pressure in the fluids of an organism by the control of water and salt concentrations.) It is often concentrated in the vacuole of the plant and it is moved across membranes to help draw ...
