In this article we will discuss about the process of respiration in bacteria. Like other living things bacteria respire. They oxidize food materials present in the cytoplasm to obtain energy. Most bacteria make use of the free oxygen of the atmosphere or oxygen dissolved in the liquid environment. They are called the aerobes or aerobic bacteria. They are so called [...]
In this article we will discuss about the nutrition needed by autotrophic and heterotrophic bacteria. Most of the bacteria lack chlorophyll. They are thus unable to synthesize organic compounds which they need as food from simple inorganic substances. They obtain these from the external sources readymade. For this reason these organisms are put in the category of heterotrophic plants. However, [...]
