Which type of cell lacks a nucleus?

• A. Eukaryotic cell
• B. Plant cell
• C. Prokaryotic cell
• D. Fungal cell

Answer: (C)

The type of cell that lacks a nucleus is prokaryotic. Prokaryotic cells do not have a membrane-bound nucleus; their genetic material is located in the cytoplasm in a region called the nucleoid rather than inside a nuclear envelope. They are typically simpler and smaller and also lack many membrane-bound organelles. Bacteria and archaea are examples of prokaryotes.

In contrast, plant cells and fungal cells are eukaryotic, meaning they contain a true nucleus enclosed by a membrane, along with other membrane-bound organelles. This distinction between having a nucleus (eukaryotic) and not having one (prokaryotic) is a fundamental difference in cellular organization.
