The Kingdom Protista includes diverse kinds of predominantly water-dwelling unicellular eukaryotic microorganism. Protists, like Monerans, have an immense reproductive potential. In an optimal environment, they may reproduce several times a day. This is mainly by asexual reproduction, using the process of mitosis. However, they also reproduce sexually.

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. It was discovered by Nobel Prize winners, Joshua Lederberg and Edward L. Tatum in 1946.
