The following points highlight the seven main components of Bacteria Cell. The components are: 1. Cell Envelope 2. Cytoplasm 3. Nucleoid 4. Plasmids 5. Inclusion Bodies 6. Flagella 7. Pili and Fimbriae. Component # 1. Cell Envelope: It is the outer covering of protoplasm of bacterial cell. Cell envelope consists of 3 components— glycocalyx, cell wall and cell membrane. (i) [...]
In this article we will discuss about:- 1. Structure of a Bacterial Cell 2. Beneficial Activities of Bacteria 3. Role in Industry. 1. Structure of a Bacterial Cell: It is a prokaryotic cell in which genetic material is not organised in the form of nucleus but instead lies freely in a naked super-coiled state in the cytoplasm whence it is [...]
The following points highlight the five main types of autotrophic and heterotrophic nutrition in bacteria. The types are: 1. Photoautotrophic Bacteria 2. Chemoautotrophic Bacteria 3. Saprophytic Bacteria 4. Symbiotic Bacteria 5. Parasitic Bacteria. Type # 1. Photoautotrophic Bacteria: The bacteria possess photosynthetic pigments of two types, bacteriochlorophyll and bacteriophaeophytin (chlorobium chlorophyll). The two types of pigments respectively occur in purple [...]
