Question #45250
The Question
Cellular quiescence (G0 phase) and organismal diapause share a profound biological parallel, as both represent a temporary halt in progression triggered by specific cues. Which of the following statements is INCORRECT regarding the physiological and ecological parallels between these two states?
Options
- A.
Both phenomena represent a reversible state of suspended progression where the entity becomes metabolically inactive to conserve energy during unfavorable conditions.
- B.
Somatic cells enter the G0 phase by exiting the G1 phase, whereas zooplankton enter diapause as a stage of suspended development.
- C.
While G0 is a cellular response often linked to differentiation or lack of mitogens, diapause is an organism-level ecological adaptation to escape stress in time.
- D.
Neither state represents senescence; a G0 cell can re-enter the cell cycle and a diapausing organism can resume development upon receiving appropriate cues.

Why This Question Is Tricky
Common Mistakes
Conceptual Pivot: Students frequently confuse 'suspended development or proliferation' with 'metabolic inactivity'.
The trap relies on the exact NCERT line that G0 cells are 'metabolically active', contrasting with the intuitive but scientifically incorrect assumption that a resting or dormant stage implies zero metabolism.
