Vast Diversity of Bacteria around the World

The bacterial structure is very simple in functionality; they are very complicated in behavior. Compared to many other organisms, bacteria as an assembly might show the most widespread metabolic diversity. Some kinds of the bacteria are autotrophic, that is, they synthesize their own food from inorganic or non living substrates. They may be classified as chemosynthetic autotrophic or photosynthetic autotrophic. Biology Assignment Help could elucidate that the large majority of bacteria are heterotrophs, that is, they do not synthesis their own food though depend on other non living or on dead organic matter for their food.

These bacteria are very unique as they live in some of the most harsh habitats or atmosphere like extreme salty regions, hot springs and marshy regions. Archaebacteria is also differing from other bacteria in having a dissimilar cell wall structure and this discrete feature is responsible for their survival in extreme circumstances. Methanogens are easily found in the guts of numerous ruminant animals like cows and buffaloes and they are responsible for the generation of methane from the dung of these animals.

There are thousands types of various eubacteria or true bacteria. They are characterized by the presence of a stiff or strong cell wall, and when motile, a flagellum. The cyanobacteria termed to as blue-green algae have chlorophyll similar to green plants and are Photosynthetic autotrophs. The cyanobacteria are colonial, unicellular, or filamentous, and marine or terrestrial algae. Biology assignment help states that the colonies are normally surrounded by strong sheath. They frequently generate blooms in polluted water bodies. Several of these organisms can fix nitrogen in more specific cells known as Anabaena, heterocysts, and Nostoc.

Chemosynthetic autotrophic bacteria oxidize different inorganic substances like nitrates, and ammonia nitrate and use the discharged energy for their ATP production. They play a significant role in recycling nutrients such as phosphorous, nitrogen, iron and sulphur.

Biology homework help is necessary for student in such a great competition for high marks in exams. Biology assignment help from expert professors is very helpful for all level of students for scoring high grades in examinations.
