List-I: (a) Cells with active cell division capacity (b) Tissue having all cells similar in structure and function (c) Tissue having different type of cells (d) Dead cells with highly thickened walls and narrow lumen List-II: (i) Vascular Tissues (ii) Meristematic tissues (iii) Sclereids (iv) Simple Tissue Choose the correct answer:

Answer: (C) (a)-(ii); (b)-(iv); (c)-(i); (d)-(iii). Answer: (c) (a)-(ii); (b)-(iv); (c)-(i); (d)-(iii).

  1. A.(a)-(i); (b)-(ii); (c)-(iii); (d)-(iv)
  2. B.(a)-(iii); (b)-(ii); (c)-(iv); (d)-(i)
  3. C.(a)-(ii); (b)-(iv); (c)-(i); (d)-(iii)
  4. D.(a)-(iv); (b)-(iii); (c)-(ii); (d)-(i)

Correct Answer

(C) (a)-(ii); (b)-(iv); (c)-(i); (d)-(iii)

Solution & Explanation

Answer: (c) (a)-(ii); (b)-(iv); (c)-(i); (d)-(iii). Solution: (a) Meristematic tissues retain the capacity for active cell division. (b) A simple tissue is made of one type of cell, so all cells are similar in structure and function. (c) Vascular (complex) tissues such as xylem and phloem are made of more than one type of cell. (d) Sclereids are dead sclerenchyma cells with highly thickened (lignified) walls and a narrow lumen. This gives the combination (a)-(ii), (b)-(iv), (c)-(i), (d)-(iii). NCERT Reference: NCERT Class XI, Ch 6 Anatomy of Flowering Plants, p.77, line ~29: "broadly classified into meristematic (apical, lateral and intercalary) and permanent (simple and complex)"; sclereid (dead thick-walled sclerenchyma) detail per pre-2023 The Tissues subsection.
