Which type of cells lack a nucleus?

• A. Eukaryotic Cells
• B. Prokaryotic Cells
• C. Animal Cells
• D. Plant Cells

Answer: (B)

Prokaryotic cells are characterized by their lack of a defined nucleus, which sets them apart from eukaryotic cells. Instead of being encased within a nuclear membrane, the genetic material in prokaryotic cells is found in a region called the nucleoid, which is not separated from the rest of the cell. This structural difference is significant, as it impacts the way these cells function and reproduce. Prokaryotic organisms, which include bacteria and archaea, typically have simpler cellular structures and can carry out essential life processes without the compartmentalization found in eukaryotic cells. In contrast, both animal and plant cells, categorized as eukaryotic cells, contain a nucleus that houses their DNA. Thus, the presence of a nucleus is a defining feature of eukaryotic cells, confirming that prokaryotic cells are the correct answer when identifying cells that lack a nucleus.
