Notes on Cell Membrane:- 1. Meaning of Cell Membrane 2. Nature of Cell Membrane Membrane 3. Transport Mechanisms. Meaning of Cell Membrane: The cells are bounded by a thin membrane which is not visible under the light microscope and is called plasmalemma. Plasmalemma along with the cell cement is referred to as cell membrane. Membranes are chemically lipoproteins and have [...]
In this article we will discuss about the interrelationship of the different cell membrane. It is generally believed that a close structural and functional relationship exists between the different membrane systems of the cell (Fig. 3-15). Some authors have proposed a terminology for the different membranes viz. Novikoff has suggested GERL indicating close functional relationship between Golgi Complex (G), ER [...]
The following points highlight the nine main organelles of cytoplasm. The Organelles are: 1. Endoplasmic Reticulum 2. Mitochondria 3. Plastids 4. Golgi Apparatus 5. Ribosome 6. Peroxisomes and Glyoxysomes 7. Lysosomes 8. Nucleus 9. Hydrogenosome. Organelle # 1. Endoplasmic Reticulum: The cytoplasm of a eukaryotic cell consists of an elaborate network of double membrane system called the ergastoplasm, or endoplasmic [...]
