Which one of the A. Tremendous surface area
B. Contain cell sap at a higher concentration than the surrounding soil water
C. Root hairs have thin cell walls
D. Grow downward into the soil
The downward growth of the roots is due to the gravity and does not take any part in the absorption of water. The absorption of water is facilitated by the lateral roots growing near the surface of the soil and the hairs arising from them.
