Question

which structure is found in both prokaryotic and eukaryotic cells?
○ nucleus
○ ribosome
○ golgi apparatus
○ endoplasmic reticulum

Explanation:

• Prokaryotic cells lack a nucleus, Golgi apparatus, and endoplasmic reticulum (these are membrane - bound organelles found in eukaryotes).
• Ribosomes are non - membrane - bound organelles. Prokaryotic cells have ribosomes (70S) and eukaryotic cells have ribosomes (80S in cytoplasm and 70S in mitochondria/chloroplasts). So ribosomes are present in both prokaryotic and eukaryotic cells.

Answer:

B. Ribosome
