Question

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

Answer 1

• Yes. It is because, in the stem, water and minerals move in an upward direction and food moves in a downward direction.
• The stem conducts water and minerals from the root to leaves and other parts of the plant (upward).
• The stem conducts food (upward and downward) from the leaves to other parts of the plant.
