why are cells microscopic?

Cells are microscopic in order to efficiently carry out their various functions within organisms. Being small allows for a high surface area-to-volume ratio, which is essential for the exchange of nutrients, gases, and waste products across the cell membrane. Additionally, being microscopic allows cells to move and transport materials more easily within the organism.

Furthermore, being small in size enables cells to replicate and divide quickly, facilitating growth and repair processes in multicellular organisms.Overall, the microscopic size of cells is crucial for their functionality and overall efficiency in maintaining the life and functionality of an organism.
