Can the stem of a plant be compared with a street with two-way traffic? Give reason.

Yes, the stem of a plant can be compared with a street with two ways traffic because just like a two way street that allows traffic to travel in both direction, a stem has two ways mechanism of transport i.e. one type of tubes in the stem carry water and dissolved minerals from the roots to the leaves and other parts. Another type of tubes present in the stem carry food from leaves to other parts of plant, including roots.
