Why are cells small?
🔬 Cells' size limitations unlock efficiency! Cells are small because their size is constrained by the need to maintain a high surface-to-volume ratio, which enables efficient exchange of materials and waste, and ensures proper cellular function. This size constraint allows cells to optimize resource allocation and thrive in diverse environments.
