Endoplasmic reticulum diagram: The endoplasmic reticulum (ER)

The endoplasmic reticulum (ER) is the largest membrane-bound organelle of the eukaryotes, but the prokaryotes lack these organelles. In this article we will discuss about the structure of endoplasmic reticulum . This will also help you to draw the structure and diagram of endoplasmic reticulum . 1. It was discovered by Porter (1945) as fine recticulum in endoplasm of cells and named as endoplasmic reticulum (E.R.). 2. It is a complex interconnecting system of flattened membrane-surrounded channels and vesicles (cisternae) that spreads throughout the cytoplasm of eukaryotic cells. 3. The membranes appear to be continuous ... Endoplasmic reticulum membrane may assume the form of cisternae, tubules or vesicles. The cisternae are broad, flat; membrane bound spaces arranged parallel to each other. The tubules appear in circles in the endoplasmic reticulum sections. The vesicles or sac appear as membrane-bound, isolated globose cavities. Endoplasmic reticulum can be recognized in most cells on the basis of ribosome association. Accordingly, known as smooth endoplasmic reticulum and rough endoplasmic reticulum ...
