Abstract
During photosynthesis on Hydrillaverticillata, the pH of the surrounding water is rendered slightly alkaline
and in the absence of light the pH is brought back to near neutral condition. However, if the habitat pH IS
ac~dico r alkaline due to the effluents present, this plant has a remarkable buffering capacity to bring the
habitat pH to optimum, which is near-neutral. The ability of the plant to raise the pH of the habitat from 7 to
slightly alkalinity under illumination is lost when cadmium ions are present in water. The buffering action
of the plant has been studied in (a) acidic and alkaline conditions (b) natural and distilled water and (c)
nutrient solutions under normal and artificial illumination. A typical electrophyiogram of a twig is also
included.
