A) Nutrient diffusion is most efficient for smaller cells.
B) A low surface area- to- volume ratio helps smaller cells divide easier.
C) A high surface area- to- volume ratio helps smaller cells divide easier.
D) Storage bodies within a cell enable cells to be small so they need less nutrients.
E) Intracellular inclusions demand that cell size be small.
