Question

Which of the following statements is wrong?

• A. Plants absorb only one substance at a time - water or inorganic salts.
  
• B. Water and inorganic salts are taken simultaneously by the root hairs.
  
• C. Plants take in a small quantity of mineral salts through the root hairs.
  
• D. Roots are one of the main absorbing organs of the plant.

Answer 1

The correct option is B

Water and inorganic salts are taken simultaneously by the root hairs.

Plants absorb only one substance at a time. Plants absorb water from the soil by osmosis. Mineral salts are absorbed by the root through the process of diffusion. Inorganic salts are absorbed in the form of ions. Each type of ion is taken up according to it's requirement.
