Question

Match LIST-I with LIST-II 

LIST-I		LIST-II
A.	Protoplast	I.	Ability of cell to develop into a new plant
B.	Explant	II.	Unorganized mass of cells
C.	Totipotency	III.	Naked cell
D.	Callus	IV.	Any plant tissue used to regenerate new tissue/organ/plant in vitro

Choose the correct answer from the options given below: 
 

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

Hint:

Learn the basic vocabulary of plant tissue culture: {Explant} is the start. It has {Totipotency}. It forms a {Callus}. If you remove the wall, it becomes a {Protoplast}.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
This question requires matching fundamental terms used in plant tissue culture with their correct definitions.
Step 2: Detailed Explanation:
A. Protoplast: A plant cell from which the cell wall has been completely removed, leaving only the plasma membrane as the outer boundary. It is often referred to as a III. Naked cell.
B. Explant: The piece of plant tissue or organ that is excised from the parent plant and placed into tissue culture to initiate growth. It is IV. Any plant tissue used to regenerate... in vitro.
C. Totipotency: The inherent potential of a single plant cell to divide and differentiate to form an entire new plant. It is the I. Ability of cell to develop into a new plant.
D. Callus: A growing mass of II. Unorganized mass of cells, typically produced on a solid medium in tissue culture from an explant.
Step 3: Final Answer:
The correct matches are A-III, B-IV, C-I, and D-II.
