The following points highlight the top four historical models of Plasma Membrane. The models are: 1. Lipid and Lipid Bilayer Models 2. Unit Membrane Model (Protein-Lipid Bilayer-Protein) 3. Fluid Mosaic Model 4. Dannelli Model. 1. Lipid and Lipid Bilayer Model: This model to explain the structure of plasma membrane was given by Overton, Gorion and Grendel. Previously only indirect information [...]
In this article we will discuss about the structure of plasma membrane. This will also help you to draw the structure and diagram of plasma membrane. 1. The membrane which bounds the protoplasm (Fig. 292) of the cell of all living organisms including plants and animals is known as plasma membrane or cell membrane or plasmalemma. 2. Plasma membranes range [...]
In this article we will discuss about:- 1. Meaning of Plasma Membrane 2. Structure of Plasma Membrane 3. Functions. Meaning of Plasma Membrane: The membrane enclosing a cell is called cell membrane or plasma membrane (animal cells) and plasma lemma (plant cells). It contains proteins and lipids in the ratio of 80 : 20 in bacteria on one extreme and [...]
