Final answer:
All cells have a cell membrane, genetic material, and cytoplasm, with eukaryotic and prokaryotic cells both containing DNA.
Step-by-step explanation:
All cells have several common features. One of these is a cell membrane, which acts as a barrier and controls the movement of substances in and out of the cell. Another common feature is genetic material, which can be DNA in both prokaryotic and eukaryotic cells. Additionally, all cells have cytoplasm, a gel-like substance that fills the cell and houses various organelles. These organelles perform specific functions to keep the cell alive and functioning.
