Question

question 1 - 4
which of the following statements correctly identifies a way in which prokaryotic cells are different from eukaryotic cells?
prokaryotic cells have flagella, while eukaryotic cells do not.
prokaryotic cells have chloroplasts, while eukaryotic cells do not.
prokaryotic cells only have free - floating dna, while eukaryotic cells have dna enclosed in a nucleus.
prokaryotic cells only have cell membranes, while eukaryotic cells have both cell membranes and cell walls.

Explanation:

• Prokaryotic cells have free - floating DNA (no nucleus), while eukaryotic cells have DNA enclosed in a nucleus.
• Both prokaryotic and eukaryotic cells can have flagella.
• Prokaryotic cells do not have chloroplasts (only some eukaryotic cells like plant cells have chloroplasts).
• Many prokaryotic cells have cell walls (e.g., bacteria have peptidoglycan cell walls), and some eukaryotic cells (e.g., plant cells) also have cell walls.

Answer:

Prokaryotic cells only have free - floating DNA, while eukaryotic cells have DNA enclosed in a nucleus.
