The Levels of Classification | KPCOFGS: Kingdom, Phylum, Class, Order, Family, Genes, Species |
Taxonomy | the scientific study of how all living things are classified |
Binomial Nomenclature | the naming system Linnaeus used |
Virus | is a tiny, nonliving particle that enters and then reproduces inside a living cell |
Host | is an organism that provides a source of energy for a virus or another organism |
Parasite | an organism that lives on or in a host and causes it harm |
bacteriophage | is a virus that infects nacteria |
Bacteria | single- celled organisms are prokaryotes (the genetic material in their cells is not contained in a nucleus) |

Binary Fission | one cell divides to form two identical cells, bacteria reproduced |
Asexual Reproduction- | is a reproductive process that involves only one parent and produces offspring that are identical to the parent |
Sexual Reproduction | involves two parents who combine their genetic material to produce a new organism, which differs from both parents |
Conjugation | a process in which one bacterium transfers some of its genetic material into another bacterium through a thin, threadlike bridge that joins the two cells |
