Question

Which among these conduct water and minerals from root?

• A. B
• B. A
• C. Both A and B

Answer 1

The correct option is A

B

B

Choice B is showing unidirectional flow and that is definitely xylem.

Xylem transports water and solutes from the roots to the leaves, while phloem transports food from the leaves to the rest of the plant. Most water enters through root hairs and root hairs are always turgid due to solute potential and the transport of minerals into root by active transport. The water molecules that move through the xylem are connected in a continuous “stream” and is like a one-way street, it is unidirectional and it travels along this route: soil -> roots -> stem -> leaves -> air.
