What is the mechanism of long distance transport of substances within a plant?
Diffusion
Active transport
Mass or bulk flow system
Independent movement
Solution
Long distance transport of substances within a plant cannot be done by diffusion alone as it is a slow process and can account for only short distance movement of molecules. Special long distance transport systems are necessary to move substances across long distances and at a much faster rate. The movement of substances in bulk or en masse from one point to another is known as mass flow.
