Question

Match List - I with List - II. 

List - 1		List - 1
a	Lenticels	i	Phellogen
b	Cork cambium	ii	Suberin deposition
c	Secondary cortex	iii	Exchange of gases
d	Cork	iv	Phelioderm

Choose the correct answer from the options given below.

• (a) - (iv) , (b) - (i), (c) - (iii) , (d) - (ii)
• (a) - (iii) , (b) - (i), (c) - (iv) , (d) - (ii)
• (a) - (ii) , (b) - (iii), (c) - (iv) , (d) - (i)
• (a) - (iv) , (b) - (ii), (c) - (i) , (d) - (iii)

Answer 1

The Correct Option is B

To solve this question, we need to correctly match the terms from List - I with their relevant descriptions in List - II. Let's analyze each term and identify the correct match based on biological concepts:

1. Lenticels: These are small openings on the surface of stems and other plant organs that facilitate the exchange of gases between the internal tissues and the atmosphere. Hence, lenticels are correctly matched with option (iii) Exchange of gases.
2. Cork cambium: Also known as phellogen, this is a type of meristem that produces cork (phellem) and secondary cortex. Therefore, cork cambium corresponds to option (i) Phellogen.
3. Secondary cortex: This is the tissue produced by the cork cambium, and it is known as phalloderm. So, secondary cortex matches option (iv) Phelloderm.
4. Cork: This is the outer protective tissue of the plant that prevents water loss and offers protection. The cork layer contains suberin, which is a waxy substance that makes it impermeable to gases and water. Thus, cork is matched with option (ii) Suberin deposition.

Based on the above matching, the correct answer is:

• Lenticels - (iii): Exchange of gases
• Cork cambium - (i): Phellogen
• Secondary cortex - (iv): Phelloderm
• Cork - (ii): Suberin deposition

Therefore, the correct answer is: (a) - (iii), (b) - (i), (c) - (iv), (d) - (ii).
