Prokaryotes include autotrophs and heterotrophs.
An organism that can survive on its own organic matter. Heterotrophs is a kind of organism that can't produce organic matter by itself, so it must feed on ready-made organic matter.
Prokaryotes are widely distributed in ecology, and their physiological characteristics are extremely complex. Some species can live in saturated salt solutions; Others can survive in distilled water; Some can reproduce at 0℃; Some take 70℃ as the optimum temperature; Some are completely inorganic trophic bacteria with carbon dioxide as the only carbon source; Others can only live in living cells.
Among the prokaryotic organisms that carry out photosynthesis, some will release oxygen, while others will not. Some can live in the environment above pH 10, while others can only live in the environment around pH 1. Some bacteria can only survive in an environment with sufficient oxygen supply, while others are extremely sensitive to the toxic effects of oxygen.
Some can use inorganic nitrogen, and some need organic nitrogen to grow; Others can use molecular nitrogen as the only nitrogen source.
Extended data:
Prokaryotes include bacteria, actinomycetes and fungi; Fungi are divided into yeast, mold and edible fungi; Bacteria and actinomycetes, cyanobacteria (such as chromococcus, Nostoc commune, Tremella fuciformis, Spirulina), etc.
Prokaryote genes are divided into coding region and non-coding region.
The so-called coding region can be transcribed into corresponding messenger RNA to guide the synthesis of protein, that is, it can encode protein. The non-coding region is the opposite, but the non-coding region is essential for the expression of genetic information because the non-coding region has nucleotide sequences that regulate the expression of genetic information.
Non-coding areas are located upstream and downstream of coding areas. The most important nucleotide sequence for regulating the expression of genetic information is the binding site of RNA polymerase located upstream of the coding region. RNA polymerase catalyzes the transcription of DNA into RNA and can recognize and bind binding sites in regulatory sequences.
