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 [...]

The eukaryotic cells are found in most of the algae, fungi, protozoa and all the higher plants and animals. Irrespective of their variable shapes and sizes, these cells display the following fundamental components (Fig 1.15): 1. Cell wall and Plasmalemma or cytoplasmic membrane, 2. Cytoplasm and 3. Nucleus. The eukaryotic cells contain extensive internal membrane systems such as endoplasmic reticulum [...]
