Bacteria: Structure and Role (With Diagram)

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 [...]

Autotrophic and Heterotrophic Nutrition in Bacteria

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 [...]
