Like the development of the flagellum for movement, sexual reproduction in protists involving meiosis, syngamy and zygote formation appears to have been a major evolutionary innovation by the primitive protists. This innovation has made a profound effect on more complex organisms.
In Industrial microbiology, microbes are used to synthesise a number of products valuable to human beings. This industry has provided products that have profoundly changed our lives and life spans. These products include beverages, food additives, products for human and animal health, and biofuels.
Several Bacteria (like Escherichia Coli) exhibit a form of sexual reproduction called Bacterial Conjugation. It is the transfer of genetic material between bacterial cells by direct cell-to-cell contact or by a bridge-like connection between two cells.
