Which term describes cells that do not have a nucleus or membrane-bound organelles?

• A. Eukaryotic
• B. Virus
• C. Fungi
• D. Prokaryotic

Answer: (D)

Cells that do not have a nucleus or membrane-bound organelles are described as prokaryotic. In these cells, DNA isn’t enclosed in a nucleus; it typically sits in a region called the nucleoid in the cytoplasm. They lack membrane-bound structures such as mitochondria or endoplasmic reticulum, making them simpler in organization than eukaryotic cells. Bacteria and archaea are examples of prokaryotes. By contrast, cells that do have a nucleus and organelles are eukaryotic, with fungi being a common example of that group. Viruses aren’t cells at all and don’t fit the concept of prokaryotic or eukaryotic cells. So, prokaryotic is the term that best describes cells lacking a nucleus and membrane-bound organelles.
