The following points highlight the four main components of the Cytoplasm. The components are: 1. Groundplasm or Cytoplasmic Matrix 2. Organoids or Organelles 3. Inclusions or Ergastic Substances 4. Vacuoles. Cytoplasm: Component # 1. Groundplasm or Cytoplasmic Matrix: In light microscopy the term groundplasm refers to the liquid fraction of cytoplasm in which other components of the protoplast are [...]
Mycoplasmas are tiny, virus-like non-motile prokaryotic organisms. They are the simplest and smallest known organisms capable of growing on cell free laboratory culture media containing sterols. Mycoplasmas lack definite cell wall and are characteristically delimited by a distinct, soft, flexible trilaminar unit membrane of lipoprotein. Because of the soft and plastic membrane they can assume a variety of shapes and [...]
In this article we will discuss about the Structure of Cyanobacteria (Blue Green Algae). Blue-green algae are the most primitive organisms in the plant kingdom and show typical prokaryotic organization (Fig. 1.13). A typical cell of blue-green algae is composed of the following components: 1. Outer cellular covering. 2. Cytoplasm. 3. Nucleic material. 1. Outer Cellular Covering: The outer covering [...]
