Why are tiny cells more efficient to basic unit of life than a large cell?

Tiny cells are more efficient than large cells primarily due to their higher surface area-to-volume ratio. This allows for more effective transport of nutrients, gases, and waste across the cell membrane. Smaller cells can also replicate and respond to environmental changes more quickly, enhancing their adaptability and survival. Additionally, cellular processes like diffusion occur more rapidly in smaller cells, contributing to overall metabolic efficiency.
