in which cell ribosome are of large size and present either on endoplasmic reticulum or free in cytoplasm?
Correct answer: B. eukaryotic
- A. prokaryotic
- B. eukaryotic
- C. both
- D. all the above
Explanation
Eukaryotic cells have larger 80S ribosomes, either attached to rough endoplasmic reticulum or free in the cytoplasm. Prokaryotes have smaller 70S ribosomes and do not possess endoplasmic reticulum, so “both” is incorrect.

About Prokaryotic and Eukaryotic Cells
Prokaryotic cells lack a membrane-bound nucleus and complex membrane-bound organelles, whereas eukaryotic cells contain a nucleus, specialized organelles and a cytoskeleton. Comparisons include DNA organization, ribosomes, cell walls, size, division and examples such as bacteria, archaea, protists, fungi, plants and animals.
