Description: The author has attempted to present a comprehensive and unified approach to plant physiology, with emphasis on the energetics of transport processes. The present approach is in line with P. Mitchells theory of proton motive force as the source of energy for symport and antiport processes in all cell membranes. We have been able to thereby formulate a comprehensive theory of plant transport regulated by the diverse metabolic activities of plant tissues. We not only resolve the problem of pH-stating in the two sets of tissues but also obtain the metabolic source of energy for transport in plants. We see that plant transport is not driven by inanimate agencies like transpiration and osmotic pressure alone but is rather governed by plants own metabolism. As living organisms, plants have to be in a position to acquire nutrients of the kind and at the rate at which these are required and hence both sinks and sources must regulate transport by their own activity in harmony with their metabolism at any time of the day and season. It has been probably the lack of recognition of the wide and diverse faculties of plants by earlier physiologists who assigned plants an inferior status of living state compared to species of animal kingdom.
