In this article we will discuss about:- 1. Types of Plastids in Cell 2. Structure of Chloroplastid 3. Origin 4. Function. Types of Plastids in Cell: Plastids may be coloured or colourless and are of three types. The leucoplasts are the colourless plastids principally serving the purpose of storage. On the basis of nature of storage compound, leucoplastids are amyloplasts [...]
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 [...]
Quick Notes on Mitochondria:- 1. Introduction to Mitochondria in Cell 2. Origin of Mitochondria in Cell 3. Structure 4. Function. Introduction to Mitochondria in Cell: Mitochondria are membrane bound cell organelles, associated with cellular respiration, the source of energy, being termed as power houses of cell. Mitochondria, discovered by Benda (1898), are present in eukaryotic cells. These are bean-shaped organelles, [...]
