Lecture Notes on Lysosomes

Subject Matter of Lysosomes: In the cytoplasmic matrix of the cells, there occur variously shaped bodies usually bounded by a single surface membrane and containing hydrolytic enzymes. These are called lysosomes. These enzyme containing bodies play important role in the digestion or lysis of intracellular substances, so they are called lysosomes. Lysosomes were first reported by Christian de Duve and [...]

Heterochromatin and Euchromatin in the Nucleoplasm

In this article we will discuss about the Heterochromatin and Euchromatin in the Nucleoplasm. In the nucleoplasm of interphase nucleus a dark staining network is seen which is formed of chromatin. When chromatin is stained by various procedures such as the feulgen reaction which is specific for DNA and examined under light microscope, some regions are stained darkly whereas the [...]

5 Main Components of the Nucleus (With Diagram)

The following points highlight the five main components of the nucleus. The components are: 1. Nuclear envelope 2. Nuclear Sap or Nucleoplasm 3. Nucleolus 4. Chromatic Reticulum 5. Chromosomes.   Nucleus: Component # 1. Nuclear Envelope: The nuclear membrane or karyotheca is the outer boundary of the nucleus. It is found in the nuclei of all the eukaryotic cells. Electron [...]
