The following points highlight the nineteen important functions of cell membranes. 1. The cell membranes cause compartmentalization. As plasma membranes they separate the cells from their external environment. As organelle coverings, they allow the cell organelles to maintain their identity, internal environment and functional individuality. 2. Plasma membrane protects the cell from injury. 3. The membranes allow the flow of [...]
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 [...]
