Question

Match List I with List II 

Choose the correct answer from the options given below: 
 

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

Hint:

Suffixes help: "-ine" often implies amino acids or vitamins, while names like Zeatin or Kinetin refer to Cytokinins.
Picloram and Dicamba are common "synthetic auxin" herbicides.

Answer 1

The Correct Option is B

Step 1: Understanding the Question:
The question asks to categorize various biochemical substances into their respective functional groups (hormones, vitamins, or amino acids).

Step 2: Detailed Explanation:

• Zeatin (A-III): It is a naturally occurring Cytokinin first isolated from maize (Zea mays). It promotes cell division and delay of senescence.

• Picloram (B-I): It is a synthetic Auxin (often used as a herbicide). Like 2,4-D, it mimics natural auxins to disrupt plant growth at high concentrations.

• Thiamine (C-IV): It is Vitamin B1. In plant tissue culture, it is an essential component of the media (like MS media) for the proper growth of explants.

• Glutamine (D-II): It is an Amino acid. It is frequently added to plant culture media as an organic nitrogen source to stimulate growth and development.
Final Answer:
Matching: A-III, B-I, C-IV, D-II. This corresponds to option (B).
