Question

which statement is most accurate?
prokaryotic and eukaryotic cells have the same structures.
eukaryotic cells have a nucleus; prokaryotic cells do not.
prokaryotic cells have many organelles.
eukaryotic cells are always single - celled.

Explanation:

• Prokaryotic cells lack a nucleus and membrane - bound organelles, while eukaryotic cells have a nucleus and various organelles.
• Prokaryotic and eukaryotic cells do not have the same structures. Prokaryotic cells have fewer and simpler structures.
• Prokaryotic cells do not have many organelles. They have only a few simple structures like ribosomes.
• Eukaryotic cells can be single - celled (e.g., yeast) or multicellular (e.g., plants and animals).

Answer:

Eukaryotic cells have a nucleus; prokaryotic cells do not.
