Question

Plants absorb mineral salts from the soil solution through

• A. A semipermeable membrane into the cytoplasm
• B. Perforation at the apex of root hair cells
• C. The cell wall which is semipermeable
• D. None of the above

Answer 1

The correct option is A A semipermeable membrane into the cytoplasm

Plant root hair cells are living cells surrounded by a semipermeable membrane. The cell wall is fully permeable and does not regulate the access of mineral ions to the cells of root hair. Actual absorption occurs through the semipermeable membranes of root hair cells.

So, the correct answer is option A.
