Question

Which of the following is a characteristic of prokaryotic cells?

• A. They have a well-defined nucleus.
• B. They lack a plasma membrane.
• C. They have ribosomes but no membrane-bound organelles.
• D. They have a mitochondria.

Hint:

Prokaryotic cells are simpler and smaller than eukaryotic cells and lack membrane-bound organelles, including the nucleus.

Answer 1

The Correct Option is C

Prokaryotic cells, which are simple, single-celled organisms, are characterized by the absence of a membrane-bound nucleus and other organelles like mitochondria and the endoplasmic reticulum. Nevertheless, they possess ribosomes, the cellular machinery for protein synthesis. In contrast to eukaryotic cells, which feature a clearly defined, membrane-enclosed nucleus, prokaryotes house their genetic material in a single, circular chromosome within a region known as the nucleoid.Consequently, prokaryotic cells contain ribosomes but do not have membrane-bound organelles.
