Content: The maintenance of such a dynamic equilibrium between the oceans and the atmosphere is the principal factor for the constant value of carbon dioxide concentration of the atmosphere. Absorption of Carbon Dioxide: ADVERTISEMENTS: Carbon dioxide in the air surrounding the leaves ultimately reaches the chloroplasts. Its inward diffusion path is through the stomata to the intercellular spaces, through walls of palisade and spongy parenchyma cells to the cytoplasm and thereafter into the chloroplasts. The walls of palisade and spongy parenchyma possess water. Carbon dioxide dissolves in water and ultimately passes through the walls in aqueous solution. Carbon Dioxide Concentration: If light intensity and temperature are favourable, the carbon dioxide of the atmosphere limits the rate of photosynthesis. The workers like Kreuslar (1887), Brown and Escombe (1902) and Pantanelli (1903) investigated that there is an increase in the rate of photosynthesis with an increase in the concentration of carbon dioxide at the lower levels of carbon dioxide concentrations.
