Introduction:-
Have you ever wondered how water reaches the top of tall trees or for that matter how and why substances move from one cell to the other , whether all substances move in a similar way , in same direction and whether metabolic energy is required for moving substances.Plants need to move molecules over very long distances , much more than animals do.
