What term best describes a cell that has a nucleus and other membrane-bound organelles?

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

Answer: (A)

Having a nucleus and other membrane-bound organelles is a hallmark of eukaryotic cells. In these cells, the genetic material is enclosed by a nuclear envelope, and internal structures like mitochondria, endoplasmic reticulum, and Golgi apparatus are membrane-bound, creating compartments that organize different processes. This organization contrasts with prokaryotic cells, which lack a true nucleus and internal membranes, so their DNA sits in a nucleoid region rather than being enclosed in a membrane. A plant cell is an example of a eukaryotic cell, but that term is broader and includes animal, fungal, and protist cells as well. So the best description for any cell with a nucleus and membrane-bound organelles is a eukaryotic cell.
