Question: are prokaryotic and eukaryotic cells the same size?
Answer: At 0.1 to 5.0 μm in diameter, prokaryotic cells are significantly smaller than eukaryotic cells, which have diameters ranging from 10 to 100 μm (Figure 4.2. 2). The small size of prokaryotes allows ions and organic molecules that enter them to quickly diffuse to other parts of the cell.
