Final answer:
Eukaryotic cells are larger than prokaryotic cells due to the presence of a nucleus, organelles, and a lower surface-to-volume ratio.
Step-by-step explanation:
Eukaryotic cells are generally larger than prokaryotic cells due to a combination of factors. Firstly, eukaryotic cells have a nucleus, which is surrounded by a membrane. This nucleus contains the cell's DNA and controls its activities. Secondly, eukaryotic cells have organelles, which are membrane-bound compartments that perform specific functions. These organelles allow for greater compartmentalization and specialization within the cell. Lastly, prokaryotic cells have a higher surface-to-volume ratio compared to eukaryotic cells.
