The following points highlight the two types of micro-bodies. The types are: 1. Peroxisomes 2. Glyoxysomes. Micro-Bodies: Type # 1. Peroxisomes: They are micro bodies which contain enzymes for peroxide biosynthesis. Peroxisomes were discovered by De Duve (1965) with the help of fractionation technique. The term was coined by De Duve in 1969. Peroxisomes are found in both plant and [...]
In this article we will discuss about the Structure and Functions of Flagella and Cilia. Structure of Flagella and Cilia: They are fine hair like movable protoplasmic processes of the cells which are capable of producing a current in the fluid medium for locomotion and passage of substances. Flagella are longer (100-200 µm) but fewer. Only 1-4 flagella occur per [...]
In this article we will discuss about:- 1. Discovery of Endoplasmic Reticulum 2. Types of Endoplasmic Reticulum 3. Structure 4. Functions. Discovery of Endoplasmic Reticulum (ER): It was discovered independently by Porter (1945) and Thompson (1945). The name was given by Porter in 1953. Endoplasmic reticulum is a 3-dimensional, complicated and interconnected syncrri of membrane-lined channels that run through the [...]
