Which cell type contains a nucleus and membrane-bound organelles?

• A. Bacteria
• B. Viruses
• C. Eukaryotes
• D. Prokaryotes

Answer: (C)

Having a nucleus and membrane-bound organelles is a defining feature of eukaryotic cells. In these cells, the genetic material is enclosed within a nucleus, keeping it separate from the rest of the cell, and organelles like mitochondria, the endoplasmic reticulum, and the Golgi apparatus are surrounded by membranes, allowing specialized environments for different tasks. This internal organization supports more complex functions and larger cells, as seen in plants, animals, fungi, and many protists. Bacteria and other prokaryotes lack a true nucleus and membrane-bound organelles; their DNA resides in a nucleoid region, and they don’t have enclosed compartments. Viruses aren’t cells at all, so they don’t possess a nucleus or membrane-bound organelles and must hijack a host cell to reproduce. So, the type of cell that contains a nucleus and membrane-bound organelles is a eukaryote.
