Question 7

Transport in Plants

The following processes are involved in water movement in the endodermis except

  1. A.osmosis.
  2. B.vacuolar pathway.
  3. C.diffusion.
  4. D.active transport.
Show the answer and explanation

Answer: C (diffusion.)

Explanation

Water crosses the endodermis by osmosis through the cells (vacuolar pathway), helped by active pumping of salts; simple diffusion is not the mechanism here.
