All cells have a plasma membrane (to regulate what enters and exits), genetic material (either DNA in a nucleus or nucleoid region), and cytoplasm (the gel - like substance inside the cell). However, a cell wall is not present in all cells. Animal cells, for example, do not have a cell wall. Plant cells, some fungi cells, and prokaryotic cells (like bacteria) have cell walls.
