![]() ![]() The thickness of the prokaryotic cell membrane is about 7 nm. A prokaryotic cell membrane is a thin lipid bilayer. The cell membranes of prokaryotic cells have two phospholipid layers. A prokaryotic cell membrane is actually a fluid phospholipid bi-layer submerged with proteins. The cell membrane structure of a prokaryotic cell is simple it is made up of proteins and lipids called the plasma membranes. The cell membrane of prokaryotic cell Structure The main component of the cell wall of prokaryotic cells is muren or mucopeptide or peptidoglycan (1) & (5). The ribosomes of prokaryotic cells are small and the type of 70s.ġ0. The prokaryotic cells have no cytoplasmic organelles surrounded by a covering (except ribosome).ĩ. That means only DNA is present and DNA is a circular type.Ĩ. The chromosomes of prokaryotic cells are not well-organized. Prokaryotic cells do not have well-formed plastids for photosynthesis.ħ. Although the nucleus of a prokaryotic cell contains DNA molecules, there is no specific nuclear membrane or nucleolus.Ħ. The size of the prokaryotic cell is very small (0.05 to 10µm).ĥ. The cell division is completed by the method of amitosis.Ĥ. The process of cell division of prokaryotic cells is simple. The prokaryotic cell does not have a well-organized nucleus.ģ. The structure of a prokaryotic cell is very simple.Ģ. The cells that make up the body of bacteria and blue-green algae are prokaryotic type cells (2). Exampleīacteria and blue-green algae are examples of prokaryotes. Prokaryotic cells are unicellular types (4) & (2). The genetic material of these undeveloped cells is non-histone protein DNA type. DefinitionĪ cell that does not have an organized nucleus, a membranous cell organelle, and does not have chromosomes, are called prokaryotic cells. The word pro means, “Before” and the karyon means, “nut” or “kernel”. The prokaryotic word comes from two Greek words Pro and karyon. The cell membrane of eukaryotic and prokaryotic cells is the topic of the discussion below (3). On the other hand, prokaryotic cells are composed of capsules, cell walls, cell membranes, cytoplasm, genetic material, pili, and flagella. As an example, eukaryotic cells are composed of cell walls, cell membranes, nucleus, cytoplasm, and some cell organelles located in the cytoplasm. On the basis of the nucleus, the cells are classified into two types eukaryotic cells and prokaryotic cells. Cells are the building blocks of an organism’s body. The diameter of the smallest cell is about 10 micrometers. The unicellular smallest cell is mycoplasma galliseticum. The size of a cell is about 0.1 micrometer to 100 micrometers. The cells are arranged one on top of the other to form organisms. In 1665 scientist Robert Hooke first discovered the cell. The body of all these organisms is made up of tiny billions of cells that cannot be seen with the naked eye. There are many species of organisms on earth.
