Final answer:
Eukaryotic cells are more complex and have less-regulated gene expression compared to prokaryotic cells. They also require more energy due to their larger size and complexity.
Step-by-step explanation:
Eukaryotic cells are more complex than prokaryotic cells, which supports the idea that they evolved after prokaryotic cells. Eukaryotic cells have a nucleus and other membrane-bound organelles that perform specialized functions. In contrast, prokaryotic cells lack a nucleus and organelles.
Additionally, eukaryotic cells show less-regulated gene expression compared to prokaryotic cells. Eukaryotic cells have a more complex genetic regulation system, allowing for greater control over gene expression.
Furthermore, eukaryotic cells require more energy than prokaryotic cells. This increased energy demand is due to the larger size and complexity of eukaryotic cells, which require more resources to carry out their functions.
