Final answer:
All cells share a plasma membrane, cytoplasm, DNA, and ribosomes.
Step-by-step explanation:
All cells share four common components: 1) a plasma membrane, an outer covering that separates the cell's interior from its surrounding environment; 2) cytoplasm, consisting of a jelly-like cytosol within the cell in which other cellular components are found; 3) DNA, the genetic material of the cell; and 4) ribosomes, which synthesize proteins.
However, prokaryotes differ from eukaryotic cells in several ways.
