Many species of bacteria are motile , that is capable of directed movement. Three mechanisms involved 1. For example phototaxis and chemotaxis. Bacteria also contain plasmids , which are tiny circular packets of DNA that consist of only a few genes, though many of these plasmids code for products that provide antibiotic resistance to the host bacteria. There are three mechanisms of genetic recombination in bacteria, 1.
Replication takes place by binary fission.
All major types of nutrition and metabolism evolved in prokaryotes. There are prokaryotes that can metabolize nitrogen. This last process is called nitrogen fixation and is extremely important. The evolution and use of light-absorbing pigments . Transduction of energy forms-light to chemical.
