Cell to Cell transfer of plasmids Conjugative: Plasmids that govern their own transfer by cell-to-cell contact are called conjugative(not all plasmids are conjugative) Some conjugative plasmids can transfer genetic information between distintly related organisms (between gram-positive and gram-negative bacteria, between bacteria and plant cells, and between bacteria and fungi), it is important for evolution.
