Question

Match the LIST-I with LIST-II 

LIST-I		LIST-II
A.	Auxin	I.	Undifferentiated mass of cell
B.	Protoplast	II.	6-Furfuryl amino purine
C.	Callus	III.	Indole-3 Acetic Acid
D.	Cytokinin	IV.	Pectinase

Choose the correct answer from the options given below: 
 

• A. A-I, B-II, C-III, D-IV
• B. A-I, B-III, C-II, D-IV
• C. A-III, B-I, C-IV, D-II
• D. A-III, B-IV, C-I, D-II

Hint:

Remember the key chemical examples for the two main plant hormones used in tissue culture: Auxin \(\rightarrow\) IAA (Indole-3-Acetic Acid) and Cytokinin \(\rightarrow\) Kinetin (6-Furfuryl amino purine) or Zeatin.

Answer 1

The Correct Option is D

Step 1: Concept Overview:
This question tests your ability to match plant biology and tissue culture terms with their corresponding definitions, examples, or related enzymes.
Step 2: Detailed Breakdown:
A. Auxin: A plant hormone class. The primary natural auxin is III. Indole-3-Acetic Acid (IAA).
B. Protoplast: Protoplast creation (plant cell without a cell wall) requires enzymes to break down the wall. IV. Pectinase, which digests pectin (the intercellular glue), is vital for protoplast isolation.
C. Callus: Defined as I. an undifferentiated cell mass formed during tissue culture.
D. Cytokinin: Another plant hormone class. The synthetic cytokinin Kinetin is chemically known as II. 6-Furfuryl amino purine.
Step 3: Solution:
The correct matches are A-III, B-IV, C-I, and D-II.
