KE REVIEW ~ UNIT 1

Which statement best describes a difference between prokaryotic cells and eukaryotic cells?

• The presence of both DNA and ribosomes in prokaryotic cells indicates that they are more complex than eukaryotic cells.

• The larger size of prokaryotic cells indicates that they are more complex than eukaryotic cells.

• The presence of membrane-bound organelles in eukaryotic cells indicates that they are more complex than prokaryotic cells.

• The larger size of eukaryotic cells indicates that they are more complex than prokaryotic cells.

• heat release

• gas exchange

• carbohydrate absorption

• osmotic pressure regulation
