The following points highlight the two main parts of cyanobacterial cell. The parts are: 1. Outer Cellular Covering 2. Cytoplasm. Part # 1. Outer Cellular Covering of Cyanobacterial Cell: It can be differentiated into following parts: A. Slime layer or Mucilaginous sheath: Presence of mucilaginous sheath is the characteristic feature of cyanobacteria. It consists of fibrils reticulately arranged within the [...]
In this article we will discuss about the structure of cyanobacteria. This will also help you to draw the structure and diagram of cyanobacteria. 1. A gelatinous sheath, made up of homogeneous surface, is present in all the Cyanobacteria. It may be thin (e.g., Anacystismontana) or thick and well developed (e.g., Anabaena). The mucilaginous sheath is made up of many [...]
In this article we will discuss about:- 1. Meaning and Characters of Cyanobacteria 2. Classification of Cyanobacteria 3. Reproduction 4. Parasexuality 5. Heterocyst 6. Economic Importance. Meaning and Characters of Cyanobacteria: The cyanobacteria (the earlier blue-green algae), or the blue-green bacteria, represent a group of photosynthetic, mostly photolysis-mediated oxygen-evolving monerans (prokaryotes). These are the only organisms able to perform oxygenic [...]
