• a substance that can't be broken down into simpler chemical substances

• a microscopic, unicellular organism

What are the differences between a prokaryotic cell and a eukaryotic cell? SBG 2.0

• eukaryotic cells and prokaryotic cells both have a nucleus, but only eukaryotic cells have membrane-bound organelles

• prokaryotic cells and eukaryotic cells both have a nucleus, but only prokaryotic cells have membrane-bound organelles

• eukaryotic cells have a membrane-bound nucleus and membrane-bound organelles, whereas prokaryotic cells do not have a nucleus or membrane-bound organelles
