Neco 2024 Biology Question 5 diagram

The diagram shows the main transport pathways in a typical dicot leaf. Arrow 1 indicates the movement of water from the root to the leaf, while Arrow 2 shows the movement of photosynthates from the leaf to the root. Identify the tissue through which water moves in Arrow 1 and state the primary physical mechanism that drives this movement.

Answer Options

A. Water moves through the phloem; the movement is driven by pressure flow (mass flow).
B. Water moves through the xylem; the movement is driven by root pressure.
C. Water moves through the bundle sheath; the movement is driven by osmotic diffusion.
Correct Answer D. Water moves through the xylem; the movement is driven by transpiration pull (cohesion‑tension).
Correct Answer
D
Correct Option:
Water moves through the xylem; the movement is driven by transpiration pull (cohesion‑tension).
