1. 1.

   Which of the following best explains why an actively growing cell must eventually undergo division rather than simply increasing its volume indefinitely?

   • A) The plasma membrane becomes completely rigid and prevents the transcription of essential metabolic genes.
   • B) Nuclear DNA progressively degrades as cytoplasm volume increases, halting the synthesis of structural proteins.
   • C) Cell division is triggered primarily to reduce the total chromosome number by half in somatic tissue cells.
   • D) The surface area-to-volume ratio decreases, limiting the transport of sufficient nutrients and wastes across the membrane.
