- B.A-III, B-IV, C-II, D-I
- C.A-III, B-IV, C-I, D-II✓
- D.A-IV, B-III, C-II, D-I
Correct Answer
(C) A-III, B-IV, C-I, D-II
Solution & Explanation
Answer: (C) A-III, B-IV, C-I, D-II. Solution: (A) Conjunctive tissue = the parenchyma lying between xylem and phloem (III). (B) Casparian strips = water-impermeable suberin deposition on endodermal cell walls (IV). (C) Subsidiary cells = epidermal cells specialised in the vicinity of the guard cells (I). (D) Starch sheath = the starch-rich endodermis of the dicot stem (II). This gives A-III, B-IV, C-I, D-II. NCERT Reference: NCERT Class XI, Ch 6 Anatomy of Flowering Plants — p.74, line ~17: "The parenchymatous cells which lie between the xylem and the phloem are called conjuctive tissue"; p.74, line ~9: walls of endodermal cells "have a deposition of water-impermeable, waxy material suberin in the form of casparian strips"; p.72, line ~30: "a few epidermal cells, in the vicinity of the guard cells become specialised... and are known as subsidiary cells"; p.75, line ~10: "The cells of the endodermis are rich in starch grains and the layer is also referred to as the starch sheath."
