1.	Assertion : Apical and intercalary meristems contribute to the growth in length, while the lateral meristems bring increase in girth in maize. Reason : Apical and intercalary meristems always increase the height of plants.A. If both Assertion and Reason are true and Reason is the correct explanation of Assertion.B. If both Assertion and Reason are true, but Reason is not the correct explanation of the Assertion.C. If Assertion is true, but Reason is false.D. If Assertion is false, but Reason is true.
Answer» Correct Answer - D Apical and intercalary meristems always increase in the height of plant and lateral meristem, it is responsible for secondary growth (increase in girth), but secondary growth does not occur in monocots, e.g. maize.
