Cells stay small mainly to maintain

AA small surface-area-to-volume ratio for storage
BA large surface-area-to-volume ratio for diffusion
CA constant temperature inside their nucleus
DA balanced osmotic pressure across the cell wall
Answer & Solution
Correct answer: B. A large surface-area-to-volume ratio for diffusion
1. The chapter section 2.5 lists two reasons cells stay small. 2. Rapid communication inside the cell is one. 3. A large surface-to-volume ratio for diffusion is the other. 4. So option A is correct. _Source: Selina Concise Biology Class 9, Ch 2 Cell, the Unit of Life (Mistral OCR'd PDF), section 2.5_
