Which of the following does not play any role in the movement of water through the xylem?

Options

  1. ACapillarity
  2. BRoot pressure
  3. CH+H^{+}/ATPase pump at the xylem element membrane
  4. DTranspirational pull

Correct answer

C. H+H^{+}/ATPase pump at the xylem element membrane

Step-by-step solution

ATPase pumps are found on the membranes of the living component i.e. cell or organelle. Because xylem is a dead tissue through which conduction of water occurs, therefor no ATPase action is found in the xylem.
