What do cells have in common

All cells share four common components:

a plasma membrane, an outer covering that separates the cell's interior from its surrounding environment

cytoplasm, consisting of a jelly-like region within the cell in which other cellular components are found

DNA, the genetic material of the cell

ribosomes, particles that synthesize proteins. However, prokaryotes differ from eukaryotic cells in several ways.

All cells have these four parts in common: a plasma membrane, cytoplasm, ribosomes, and DNA.
