Which cells lack a true nucleus and organelles; have a cell wall

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

Answer: (D)

Prokaryotic cells are characterized by not having a true nucleus or membrane-bound organelles, with their DNA located in a nucleoid region rather than inside a nucleus. They also typically have a cell wall, which provides structure and protection. This combination—no true nucleus or membrane-bound organelles and the presence of a cell wall—fits prokaryotic cells, such as bacteria and archaea. In contrast, eukaryotic cells have a defined nucleus and membrane-bound organelles, and plant and animal cells are examples of that group (plants have cell walls too, but they still contain a nucleus and organelles).
