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 lack a true nucleus and have free - floating DNA, while eukaryotic cells have DNA enclosed in a nucleus. Prokaryotic cells can have flagella, eukaryotic cells like sperm also have flagella. Eukaryotic plant cells have chloroplasts, not prokaryotic cells. Some eukaryotic cells (animal cells) have only a cell membrane, and some prokaryotic cells have cell walls.

Answer:

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