Answer49 - The great scientist J.C. Bose proved that plants also have life and respond like any other living being. Plants inhale the Carbon Dioxide and exhale Oxygen during the day whereas they give out Carbon Dioxide and take in oxygen in the nights. Unlike other plants ’Tulasi’ has the tendency to exhale oxygen both in the day and night.Oxygen coming out from ‘Tulasi’ purifies the polluted air surrounding the premises of the house. In halingsuch pure air reduce the effect of pollution in the mind. This enables for a healthy thinking process. A positive nature of decision making gets developed.
