In this article we will discuss about the Structure of a Bacterial Cell. It is a primitive type of cell in which genetic material is not organised in the form of nucleus but instead lies freely in a naked super-coiled state in the cytoplasm whence it is known as pro-chromosome or nucleoid. Prokaryotic (= prokaryotic) cells are known for their [...]
The following points highlight the seven important components of bacterial cell. The components are: 1. Cell Envelope 2. Cytoplasm 3. Nucleoid 4. Plasmids 5. Inclusion Bodies 6. Flagella 7. Pili and Fimbriae. Bacterial Cell: Component # 1. Cell Envelope: It is the outer covering of protoplasm of bacterial cell. Cell envelope consists of 3 components— glycocalyx, cell wall and cell [...]
In this article we will discuss about the meaning and composition of nucleoid. Meaning of Nucleoid: The genetic material of prokaryotic (bacterial) and eukaryotic cells differ variously and, probably, the most striking difference between them is the manner in which the genetic material is packaged. Eukaryotic cells possess two or more chromosomes contained within the 'nucleus' whereas the prokaryotic cells [...]
