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 [...]
In this article we will discuss about the structure of plasma membrane in bacterial cell. This will also help you to draw the structure and diagram of plasma membrane. Structure of Plasma Membrane: The plasma membrane is approximately 7.5 nm (0.0075 µm) thick, forms the limiting boundary of the cell and is made up of phospholipids (about 20-30%) and proteins [...]
In this article we will discuss about the structure and components of bacterial cell. Structure of Bacterial Cell: Bacterial cells (prokaryotic cells) are structurally much simpler than eukaryotic cells and the two cell types are compared in Table 3.2. They consists of various cell surface structures, cell wall, plasma membrane, many cytoplasmic inclusions, and the bacterial chromosome (nucleoid). Except some, [...]
