Mitochondria: Ultrastructure, Function and Reproduction | Cytoplasm

In this article we will discuss about:- 1. Ultrastructure of Mitochondria 2. Function of Mitochondria 3. Reproduction. Ultrastructure of Mitochondria: In 1953, Palade and Sjostrand independently described the ultrastructure of mitochondria. Mitochondria are bounded by an envelope consisting of two concentric membranes, the outer and inner membranes. The space between the two membranes is called inter-membrane space. A number of [...]

3 Main Classes of Protein Fibers in Cytoskeleton | Cell

The following points highlight the three main classes of protein fibers in cytoskeleton. The classes are: 1. Microtubules 2. Actin Filaments 3. Intermediate Filaments. Protein Fibers in Cytoskeleton: Class # 1. Microtubules: Microtubules are long thread-like structures measuring about 25 nm in diameter; their length varies up to several millimeters. Microtubules have the following two main properties: (i) Long and [...]

Plasma Membrane: Subject Matter and Functions (With Diagram)

In this article we will discuss about the Plasma Membrane:- 1. Subject Matter of the Plasma Membrane 2. Chemical Composition of Plasma Membrane 3. Specialized Structure 4. Functions. Subject Matter of the Plasma Membrane: The protoplasm of the cell is bounded by an exceedingly thin elastic, semi-permeable living limiting membrane called the plasmalemma or plasma membrane or cytoplasmic membrane or [...]
