Question

can the stem of a plant be compared with a two way traffic on street

Answer 1

Yes because it has the xylem and the phloem which carry food and water in opposite directions like traffic on a 2way road

Answer 2

Yes we can compare the stem of a plant with two way traffic on street.  

Explanation:

Two way traffic on street refers to the road through vehicles move in both directions. One side they enter and on the other side they exit. Likewise in plants, stem acts as a bridge between leaves and roots. It transports water from root to upper region of the leaves through xylem, whereas it sends food and other nutrient from leaves to the root through phloem.
