What are groups of small cells better than one large cell at moving material in and amp out?

Groups of small cells are better than one large cell at moving materials in and out due to their higher surface area-to-volume ratio. This increased ratio allows for more efficient diffusion and transport of substances across the cell membrane. Additionally, smaller cells can more effectively utilize cellular processes like endocytosis and exocytosis, facilitating quicker responses to environmental changes. This organization also allows for specialization of functions among different cell types within a multicellular organism.
