Plants need 02 for repiration just like animals. Plants have wonderous systems to move liquids but, this system doesn't participate in moving the gases. Almost everyone is aware of how the Co2 is taken into the plant in the leaves through the stomata.Leaves are well equiped to take are of their own gas exchanges. The distance these gases must diffuse in the plants is extremely small. Every living cell in the plant is relatively close to the surface. This arrangement is fairly obivious in leaves. The other living cells are just below the surface of the bark. Most of the living cells have at least part of their surface exposed to the ambient air. The loose packing of these cells in the parenchyma are interconnected with air space. Gases diffuse through these air spaces thousands of times more effeciently then through liquids. When the gases, 02 or C02 reach these air pockets they diffuse rapidly and efficiently.They also pass through the cell walls and plasma membranes by a method called ...moreAnswered by Psycho, 15 Feb '13 11:38 am
