Which one of the following organelle is found in both prokaryotic and eukaryotic cells?
Correct answer: D. Ribosome
- A. Centriole
- B. Endoplasmic Reticulum
- C. Nucleus
- D. Ribosome
Explanation
Ribosomes are the correct answer because they are non-membranous organelles that synthesize proteins and are found in both prokaryotic and eukaryotic cells. In contrast, centrioles, the endoplasmic reticulum, and the nucleus are membrane-bound organelles that are characteristic of eukaryotic cells and are absent in prokaryotic cells.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
