Question

what is the main difference between prokaryotic and eukaryotic cells? (1 point)
prokaryotes use rna instead of dna.
prokaryotes lack a cell membrane on the outside.
prokaryotes lack membrane-bound organelles.
prokaryotes lack ribosomes to make proteins.

Explanation:

• Analyze each option:
• Option 1: Both prokaryotes and eukaryotes use DNA as genetic material (some viruses use RNA, but prokaryotes are cells with DNA), so this is incorrect.
• Option 2: All cells (prokaryotic and eukaryotic) have a cell membrane, so this is incorrect.
• Option 3: Prokaryotic cells do not have membrane - bound organelles (like nucleus, mitochondria, etc.), while eukaryotic cells do. This is a key difference.
• Option 4: Prokaryotes have ribosomes to synthesize proteins, so this is incorrect.

Answer:

C. Prokaryotes lack membrane - bound organelles.
