Prokaryotic Cell Structures
Prokaryotic cells are simple, single-celled organisms that do not have a membrane-bound nucleus. They have a few key structures that help them carry out essential functions, but they lack some of the more complex organelles found in eukaryotic cells.
Cell Wall
- Prokaryotic cells have a rigid cell wall that provides structure and protection to the cell.
- The cell wall is made of peptidoglycan in bacteria and other unique materials in archaea.
Plasma Membrane
- The plasma membrane is a semi-permeable barrier that surrounds the cell and controls the flow of molecules in and out.
- It is made of a lipid bilayer with embedded proteins that help with various cellular processes.
Ribosomes
- Ribosomes are the cellular machinery responsible for protein synthesis.
- Prokaryotic cells have ribosomes that are smaller than those found in eukaryotic cells, but they still perform the same function.
Mitochondria
- Mitochondria are membrane-bound organelles that are the powerhouse of eukaryotic cells, producing ATP through cellular respiration.
- Prokaryotic cells do not have mitochondria; instead, they generate energy through other means, such as glycolysis or fermentation.
In conclusion, prokaryotic cells do not have mitochondria, which is a key organelle found in eukaryotic cells for energy production. This distinction is an important characteristic that helps differentiate prokaryotic cells from eukaryotic cells.

Mitochondria are organelles found in eukaryotic cells and are responsible for energy production. Prokaryotic cells lack mitochondria.
