Which statement accurately compares typical cell sizes?

• A. Prokaryotic cells are larger than eukaryotic cells.
• B. Eukaryotic cells are 0.2-2.0 micrometers.
• C. Prokaryotic cells are 0.2-2.0 micrometers in diameter.
• D. Prokaryotic cells are 0.2-2.0 micrometers in diameter; eukaryotic cells are 10-100 micrometers.

Answer: (A)

Typical cell sizes show prokaryotic cells are smaller than eukaryotic cells. Prokaryotes are usually about 0.2–2.0 micrometers in diameter, while eukaryotic cells are typically 10–100 micrometers. So, on average, prokaryotic cells are roughly ten times smaller in diameter than eukaryotic cells. The idea that prokaryotic cells are larger contradicts these standard size ranges.
