In what way do prokaryotic cells differ from eukaryotic cells?

• A. Prokaryotic cells have mitochondria while eukaryotic cells do not
• B. Prokaryotic cells lack a nucleus and membrane-bound organelles
• C. Eukaryotic cells reproduce asexually while prokaryotic cells reproduce sexually
• D. Prokaryotic cells are larger than eukaryotic cells

Answer: (B)

Prokaryotic cells are characterized by their simplicity and lack of complex structures. They do not possess a nucleus; instead, their genetic material is found in a region called the nucleoid. This fundamental difference is central to the classification of prokaryotes, which include bacteria and archaea. Additionally, prokaryotic cells typically lack membrane-bound organelles, which are distinct compartments that perform specific functions and are found in eukaryotic cells. In contrast, eukaryotic cells, which include plant and animal cells, are more complex and contain a defined nucleus that houses their DNA, as well as various membrane-bound organelles such as mitochondria, endoplasmic reticulum, and Golgi apparatus. This separation of genetic material and organelles allows for greater specialization and efficiency in eukaryotic cells. This choice accurately reflects a foundational concept in cell biology regarding the structural differences between prokaryotic and eukaryotic cells.
