Eukaryotic cells can reach above 100μm in diameter, while prokaryotic cells, like bacteria, remain

small, reaching only to about 10μm in diameter. How are eukaryotic cells able to become so much

larger than prokaryotic cells while still efficiently exchanging material through the plasma membrane?
