Which of the following is present in a prokaryotic cell?

a. mitochondrion

b. ribosome

c. nuclear envelope

d. chloroplast

The correct answer is B. Ribosome

Explanation:

In biology, cells are mainly classified as eukaryotic or prokaryotic. Each of these types of cells has different features, to begin with, eukaryotic cells are those that contain a defined nucleus and are part of both unicellular and multicellular organisms. On the opposite, prokaryotic cells do not have a defined nucleus or a nuclear envelope and are mainly present in unicellular organisms, besides this, they lack mitochondrion, Golgi apparatus or chloroplasts that are present in eukaryotic cells. However, prokaryotic cells still contain DNA, ribosomes, vesicles, and vacuoles. According to this, the one that is present in a prokaryotic cell is ribosome.
