aerobic bacteria and anaerobic bacteria

These are bacteria which are unable to manufacture their own organic food and hence are dependent on external source. These bacteria can be distinguished into three groups as follows: Saprophytic Bacteria: These bacteria obtain their nutritional requirements ..

Most of plants and animal cells respire aerobically, that is, in the presence of oxygen. However, there are certain microbes that respire in the absence of free oxygen. This respiration is called anaerobic respiration. It is also called fermentation. Among plants, it takes place..

show a primitive type of sexual reproduction called genetic recombination. In this process, the exchange of genetic materials takes place by a process called conjugation . Conjugating bacterial cells are in contact through a hollow tube called pilus. In the higher organisms, sexual reproduct..

Bacteria exhibit different modes of nutrition. On this basis, broadly two types of bacteria can be recognised autotrophic bacteria and heterotrophic bacteria..

These are bacteria which live in a mutually beneficial association with other organisms. Such bacteria derive the essential nutrients from their host organisms and in that process help the host through some of their biological activities. 1. The most familiar example of symbioti..

These are bacteria which manufacture organic compounds from inorganic raw materials utilising energy liberated from the oxidation of inorganic substances. Following are the common types of chemo autotrophic bacteria. 1. Nitrifying bacteria which derive energy by oxidi..
