Final answer:
Eukaryotic cells are larger and more complex than prokaryotic cells due to their membrane-bound nucleus and organelles, which provide specialized functions and advanced control over gene expression.
Step-by-step explanation:
True, eukaryotic cells are usually larger and more complex than prokaryotic cells. Comparing the two cell types, eukaryotic cells contain a membrane-bound nucleus and other membrane-bound organelles like mitochondria and endoplasmic reticulum, which allow for specialized functions within the cell.
In contrast, prokaryotic cells do not have a true nucleus or other membrane-bound organelles, tending to have a simpler structure. Moreover, prokaryotic cells are smaller with a higher surface-to-volume ratio, which benefits their absorption and transportation of substances. Eukaryotes, encompassing organisms from fungi to humans, feature eukaryotic cells that enable a higher level of intracellular organization and control over genetic expression.
