Which of the following structures is present in both prokaryotic and eukaryotic cells?

A. Chloroplast

B. Golgi apparatus

C. Endoplasmic reticulum

D. Cell membrane

Answer Explanation:

The main different between eukaryotic cells and prokaryotic cells is that eukaryotic cells are made up organelles bound in membranes whereas prokaryotic cells comprise of organelles that are not bound in a membrane. Besides, a nucleus is absent in the prokaryotic cells.

Despite the differences, common cell structures in both eukaryotes and prokaryotes include plasma membrane, ribosomes, cytoplasm and DNA.

Therefore, the Correct Answer is D.
