The following points highlight the eight important cytoplasmic inclusions found in bacteria. The cytoplasmic inclusions are: 1. Ribosomes 2. Polyphosphates 3. Poly-β-hydroxybutyrate 4. Glycogen 5. Gas Vacuoles 6. Magnetosomes 7. Sulfur Globules 8. Carboxysomes. Cytoplasmic Inclusion # 1. Ribosomes: Ribosomes (Fig. 5.20) in bacteria (prokaryotes) are small granular bodies of 10-20 nm in diameter freely lying in the cytoplasm and [...]
In this article we will discuss about the similarities of cyanobacteria with red algae and bacteria. Similarities of Cyanobacteria with Red Algae: (i) Flagellated or motile cells are absent in both cyanobacteria and red algae. (ii) The blue (phycocyanin) and red (phycoerythrin) pigments occurring in cyanobactena are chemically similar to those occurring in red algae and are located on phycobilisomes [...]
The ultra-structural detail of a typical cyanobacterial cell (Fig. 6.10) is the following: 1. Mucilage Sheath: The cells and filaments of most cyanobacteria are generally surrounded by a mucilaginous sheath whose thickness, pigmentation, consistency, and nature is greatly influenced by environmental factors. It is considered that these microorganisms secrete the mucilage through pores present in their cell walls. 2. Cell [...]
