NEETBotanyCell Cycle and Cell Division
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Cells in the quiescent stage ( G ₀ ) are considered to be in an inactive stage of the cell cycle. Reason (R): Cells in the G ₀ phase are metabolically inactive and permanently lose their capacity to proliferate. In the light of the above statements, choose the most appropriate answer from the optio
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
C. (A) is correct but (R) is not correct
Step-by-step solution
Assertion (A) is correct because cells that do not divide further exit the G ₁ phase and enter an inactive stage of the cell cycle known as the quiescent stage ( G ₀ ). Reason (R) is incorrect because cells in the G ₀ stage remain metabolically active. Furthermore, they do not permanently lose their capacity to proliferate; they can resume division if called on to do so depending on the requirement of the organism. Answer: (A) is correct but (R) is not correct
