Prokaryotic cells do not contain any organisms covered by bilayal membrane. Their nucleus Haploid All bacteria and arcia belong to the pre-centered national cells. Prokaryotic cells are like rooms with one room.

Cellular structure:
Plasma membrane (phospholipid diarrhea) protects the interior of the cell from its environment and acts as a communication medium and filter. Most of the primitive cells have a cell wall; The exception is microplasma (a type of bacteria) and thermoplasma (an arcion). In the case of bacteria, there is a substance called peptidoglycan in the cell wall that acts as a barrier against any external force. Cell wall protects the wall from explosion (cytolysis) due to osmotic pressure in the hypotonic environment. In the actual cell, cell walls are found to be in the cell walls (cellulose, fungal of plant cells), but the chemical composition of the wall is different. The chromosome of the primitive cells is a circular molecule. However, there is an exception to bacterial bacterial Borrelia burgdorferi. DNA molecules are concentrated in a nuclei without the actual nucleus in the original cells. They carry plasmids called Extrachromosomal DNA Elements which are usually round. Plasmid can carry some associate substances, such as antibiotic resistance. Recent studies have found that each pre-centered cell has cytokankalas, although it is primitive compared to subcutaneous cells. The length of this cell is 1 micrometre to 10 micrometres. However, from 0.2 micrometres to over 750 micrometres (Thiomargarita namibiensis).
Cell walls:
It is made up of dead or inert material. It contains chemicals such as cellulose, hemisalulose, liginin, pectin, sovereign etc. Cell wall protects from the outside hazard. The cells give firmness. Maintains the size of the cell shape. Control water and mineral movement.
Cell membrane:
The cell membrane or membrane that surrounds all protoplasm right beneath the cell membrane, is called Plasma Membrane or Kozhzilli. Because of a discrimination screen, Kozhzilli controls the water and mineral movement through circulation and separates the adjacent cells from each other.
The thick cell membrane consists of three layers. All types of membranes in different types of cells have a basic membrane with a three-dimensional membrane. Sometimes there is a thin layer and there are two thin layers on either side. The outer layer is thicker. There is a lipid in the middle of the thin layer and on the two sides there is a thick layer of protein. Lipid layer 35Å thick. And the protein layer of two sides is thick in 20Å. The thickness of the entire plasma membrane is 75Å. (20 + 35 + 20 = 75Å). Plasma membrane has a small, small hole with a diameter of 8-50Å diameter. There is no water in the plasma membrane. It has only 25% water.
NucleiSystem:
Pre-centered cells have no organized nuclei. Instead, nucleiide nuclei membranes, nuclei nets and nucleosulasabena an object can be seen. Such a nucleoide cable is made up of a long, spongy DNA molecule. It stays in the form of rings.
Ribosome:
Micro-particle composed of ribonucleoproteins located in the Rhobozom organisms. In 1943, Claude discovered Rhobozom in the first cell. In 1955, the name of the palade was named. So it is called Claydan or Pallad Dana. These are found in both pre-centric and well-centered cells. These are found in the free time of sitoplasia and in the nucleus membranes and endoplasmic reticulum gut. Rhobozom is composed of nucleic acids (RNA) and proteins (Protine). It consists of two groups. Dissolved by two magnesium and calcium.
Cell wall:
Cells that are visible in the cytoplasm are the cell cavity. Work: 1. Containing cells 2. Conserving essential waste materials. 3. Preserve food, etc.
Flasel:
There is an extended part called Flajella called a small yarn around the cell. These move and change bacteria in space.
Pillis:
Some of the proteins formed on the surface of the cell have a similar look like hair. These organs made of polythene proteins are called piilias. These help keep the body locked with the body.
