Question

Match column I with column II and select the correct option from the given codes.

Column I	Column II
A. Stele	(i). Innermost layer of cortex
B. Endodermis	(ii). Suberin
C. Casparian strips	(iii). All the tissues outer to vascular cambium
D. Bark	(iv). All the tissues inner to endodermis

• A. A-(iv), B-(i), C-(ii), D-(iii)
• B. A-(iii), B-(ii), C-(i), D-(iv)
• C. A-(i), B-(ii), C-(iii), D-(iv)
• D. A-(iv), B-(ii), C-(i), D-(iii)

Answer 1

Answer: (A)

A-(iv), B-(i), C-(ii), D-(iii)

(A) Stele - All the tissues inner to endodermis - includes pericycle, vascular bundles, and pith

(B) Endodermis - Innermost layer of the cortex - cells possess casperian strips, demarcates cortex from the stele.

(C) Casparian strips - Suberin- a chemical compound present as deposition on the cell walls of endodermis. Prevents the apoplastic movement of water.

(D) Bark - All the tissues outer to the vascular cambium, includes secondary phloem, secondary cortex, cork cambium, and cork

So, the correct answer is 'A-(iv), B-(i), C-(ii), D-(iii)'
