Which statement about prokaryotic cells is true?

Which statement about prokaryotic cells is true?

• A. They are unicellular and lack membrane-bound organelles
• B. They have a nucleus
• C. They contain mitochondria
• D. They have chloroplasts

Answer: (A)

Prokaryotic cells are simple, small cells that lack membrane-bound organelles. Their genetic material is located in a region called the nucleoid rather than inside a true nucleus. They do not have mitochondria or chloroplasts; energy production and other metabolic tasks occur in the cytoplasm or at the cell membrane. This basic, non-compartmental organization means they are typically unicellular, with each cell functioning independently (though they can form colonies or biofilms). In contrast, cells that have a nucleus and membrane-bound organelles are eukaryotic. That combination of features makes the statement true.
