Question

Assertion :Xylem transports water and dissolved mineral salts from the roots to the rest of the plant. Reason: Phloem translocates organic solutes from the leaves to various parts of the plant

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
• C. Assertion is correct but Reason is incorrect.
• D. Both Assertion and Reason are incorrect.

Answer 1

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.

Xylem is responsible for the transportation of minerals and water from roots to the rest of the plant by diffusion and suction caused due to transpiration.

Phloem translocates organic solutes from the leaves to other parts of the plant.

Unlike transport in the xylem which can be largely explained by simple physical forces, the translocation in the phloem is achieved by utilizing energy from ATP.

Both the statements are correct but the 2nd statement is not the correct explanation for the 1st statement.

So, the correct answer is option B.
