The bacteria diagram given below represents the structure of bacteria with its different parts.
Simple basic bacteria cell diagram. This will also help you to draw the structure and diagram of bacteria. Let us make an in depth study of the structure and functions of cell. However the structure of bacterial flagella is very different a long helical filament composed of.
For example a relatively thick meshlike structure that makes it possible to distinguish two basic types of bacteria. Bacterial cells prokaryotic cells are structurally much simpler than eukaryotic cells and the two cell types are compared in table 32. They have an outer cell wall that gives them shape.
The cytoplasm is enclosed by three layers the outermost slime or capsule the middle cell wall and inner cell membrane. There are two basic. In this article we will discuss about the structure and components of bacterial cell.
The major cytoplasmic contents are nucleoid plasmid ribosome mesosome etc and the cell is devoid of endoplasmic reticulum mitochondria centrosome and golgi bodies. A simple diagram of a bacterium labelled in english. A bacterial cell fig.
They consists of various cell surface structures cell wall plasma membrane many cytoplasmic inclusions and. Cell is a compartment where all the activities of life takes place. They do not possess nuclear membrane and the nucleus consists of a single chromosome of circular double stranded dna helix fig.
The cell wall plasmid cytoplasm and flagella are clearly marked in the diagram. It shows the cytoplasm nucleoid. Structure and components of a human cell.
A bacterial cell remains surrounded by an outer layer or cell envelope which consists of two components a rigid cell wall and beneath it a cytoplasmic membrane or plasma membrane. Cytoplasm of the bacterial cell is very dense due to a high content of ribosomes necessary for the rapid protein synthesis required for rapid growth some bacterial cells also have flagella. Just under the rigid cell wall is the more fluid cell membrane.
Cell wall composition varies widely amongst bacteria and is one of the most important factors in bacterial species analysis and differentiation. 25 shows a typical prokaryotic structure. Structure of bacterial cell.
After reading this article you will learn about. The cytoplasm enclosed within the cell membrane does not exhibit much structure when viewed by electron microscopy. Bacterium are unicellular prokaryotic microorganisms which divide by binary fission.
Bacteria prokaryotes are simple in structure with no recognizable organelles. Bacteria diagram representing the structure of bacteria.
