Quick Notes on Endoplasmic Reticulum! Structure of Endoplasmic Reticulum in Cell: Structurally the endoplasmic reticulum (ER) consists of cisternae, tubules and vesicles (Fig. 2.42). The cisternae are broad, flat, membrane-bound spaces arranged parallel to each other to form lamellae, which are connected with each other. The tubules are 50-1OOA in diameter. The vesicles or sacs are membrane- bound, isolated globose [...]

In this article we will discuss about:- 1. Meaning of Endoplasmic Reticulum 2. Functions of Endoplasmic Reticulum. Meaning of Endoplasmic Reticulum: It is a double membrane system found throughout the eukaryotic cell. The membrane is continuous with the nuclear membrane and the plasma membrane. The endoplasmic reticulum (ER) is absent in the prokaryotic cell. George Palade (1974) made electron microscope [...]
