Question

Assertion (A): The meristems are grown ‘in vitro’ to obtain virus-free plants from an infected plant. 
Reason (R): If the plant is infected with a virus, the roots and the stems are free of virus.

• A. Both (A) and (R) are true and (R) is the correct explanation of (A).
• B. Both (A) and (R) are true, but (R) is not the correct explanation of (A).
• C. (A) is true, but (R) is false.
• D. (A) is false, but (R) is true.

Hint:

Meristem culture is an effective method to produce virus-free plants, as meristematic tissues are typically virus-free.

Answer 1

The Correct Option is C

Step 1: In plant tissue culture, meristems are used to regenerate virus-free plants because viruses do not usually invade the actively dividing meristematic tissue.
Step 2: However, it is not true that roots and stems are free of virus in an infected plant. Thus, the reason is incorrect.
Step 3: Assertion is true but the reason is false.
