NEETBotanyCell - The Unit of Life
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): The content of the nucleolus is continuous with the rest of the nucleoplasm. Reason (R): The nucleolus is a non-membranous structure. In the light of the above statements, choose the most appropriate answer from the options given below:
Options
- ABoth (A) and (R) are correct and (R) is the correct explanation of (A)
- BBoth (A) and (R) are correct but (R) is not the correct explanation of (A)
- C(A) is correct but (R) is not correct
- D(A) is not correct but (R) is correct
Correct answer
A. Both (A) and (R) are correct and (R) is the correct explanation of (A)
Step-by-step solution
According to NCERT, the content of the nucleolus is continuous with the rest of the nucleoplasm because it is not a membrane-bound structure. Therefore, the lack of a membrane (Reason) directly explains why its contents are not isolated from the surrounding nucleoplasm (Assertion). Both statements are correct, and the Reason correctly explains the Assertion. Answer: Both (A) and (R) are correct and (R) is the correct explanation of (A)
