Question:
Assertion (A): To generate only a part of the plant from a cell is totipotency.
Reason (R): Suitable special nutrient media and sterile conditions are required in ‘in vitro’ conditions for the division of cells in explants.
Assertion (A): To generate only a part of the plant from a cell is totipotency.
Reason (R): Suitable special nutrient media and sterile conditions are required in ‘in vitro’ conditions for the division of cells in explants.
Reason (R): Suitable special nutrient media and sterile conditions are required in ‘in vitro’ conditions for the division of cells in explants.
Show Hint
Totipotency means a cell can form a whole plant, not just a part, and in vitro conditions support this process.

- Both (A) and (R) are true and (R) is the correct explanation of (A).
- Both (A) and (R) are true, but (R) is not the correct explanation of (A).
- (A) is true, but (R) is false.
- (A) is false, but (R) is true.
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Totipotency refers to the ability of a plant cell to regenerate into an entire plant, not just a part — Assertion is false.
Step 2: Sterile conditions and nutrient media are indeed required for in vitro culture of explants — Reason is true.
Step 3: Since Assertion is false but Reason is true, option (D) is correct.
Step 2: Sterile conditions and nutrient media are indeed required for in vitro culture of explants — Reason is true.
Step 3: Since Assertion is false but Reason is true, option (D) is correct.

Prevention is the frontline response to drug use. Effective interventions address the underlying conditions contributing to drug use, such as a lack of connection to family or community, instability, insecurity, trauma, mental health issues, etc. When addressed, these factors can effectively prevent the initiation of drug use and the progression to drug use disorders. Study the few key figures of drug use given below and answer the questions that follow.
