Question

Metabolically active cells have

• A. Lower nucleocytoplasmic ratio.
• B. Higher nucleocytoplasmic ratio.
• C. Higher surface: volume ratio.
• D. Both B and C.

Answer 1

The correct option is D Both B and C.

The smaller cells are more efficient and active metabolically because of higher nuclear to cytoplasmic ratio and higher surface area to volume ratio. The higher nuclear to cytoplasmic ratio allows the nucleus to have better control on metabolic activities. Whereas, the higher surface area volume ratio allows quicker exchange of materials between the cell and its surrounding.

Hence the correct option is (D)
