Both prokaryotic and eukaryotic cells share several fundamental structures. Here are the common structures found in both cell types:
- Cytoplasm - The jelly-like substance where cellular processes occur and where organelles are suspended.
- Cell Membrane - A lipid bilayer that surrounds the cell and controls the movement of substances in and out of the cell.
- Ribosomes - The molecular machines responsible for protein synthesis, although they differ in size and structure between prokaryotes and eukaryotes.
- Genetic Material - Both types of cells contain DNA, although prokaryotic DNA is typically circular and not enclosed in a nucleus, while eukaryotic DNA is linear and contained within a nuclear membrane.
These structures are essential for the basic functions of cells, regardless of whether they are prokaryotic or eukaryotic.
