In this article we will discuss about the characteristics of archaeobacteria. All organisms of this group are assumed to be descendent from a common ancestor, the so called progenote and the organisms are primitive, cellular with a rudimentary not well coordinated translation apparatus. The unique feature is in the cell membrane structure. The membrane lipids are glycerol isopronyl ethers due [...]
The below mentioned article provides notes on microbial diversity. The term 'microbial diversity' or biodiversity has become so well known that a public servant is also aware about it. Microbial diversity is defined as the variability among living organisms. The main key of microbial diversity on earth is due to evolution. The structural and functional diversity of any cell represents [...]
Subcellular structure of a fungal cell is discussed below: 1. The Cell Wall: Except slime molds (Myxomycetes), the fungal cell consists of a rigid cell wall and cell organelles. However, composition of cell wall of different fungal groups differs. Chemical analysis of cell wall reveals that it contains 80-90% polysaccharides, and remaining proteins and lipids. Chitin (a polymer of N-acetyl [...]
