Microorganisms that are similar to bacteria in size and simplicity of structure but radically different in molecular organization. They are now believed to constitute an ancient intermediate group between the bacteria and eukaryotes.

binomial nomenclature

The naming system for organisms in which each organism is given a two-part name.

The process of grouping things based on their similarities.

a bacterium of a large group typically having simple cells with rigid cell walls and often flagella for movement. The group comprises the “true” bacteria and cyanobacteria, as distinct from archaebacteria.

The scientific study of how living things are classified.

A chemical that can kill bacteria without harming a persons cells.

a member of a large group of unicellular microorganisms that have cell walls but lack organelles and an organized nucleus, including some that can cause disease.

The dense area in a eukaryotic cell that contains nucleic acids, the chemical instructions that direct the cell's activities.

An organism that provides a source of energy or a suitable environment for a virus or for another organism to live.

A small, nonliving particle that particle that invades and then reproduces inside a living cell.

An illness that can pass from one organism to another.

An organism that makes its own food.

An organism that cannot make its own food.

A form of asexual reproduction in which one cell divides to form two identical cells.

The process in which a unicellular organism transfers some of its genetic material to another unicellular organism.

An organism transfers some of its genetic material to another unicellular organism.

An organism whose cells lack a nucleus and some other cell structures.

An organism with cells that contain nuclei and other cell structures.

eubacteria	a bacterium of a large group typically having simple cells with rigid cell walls and often flagella for movement. The group comprises the “true” bacteria and cyanobacteria, as distinct from archaebacteria.
taxonomy	The scientific study of how living things are classified.
antibiotic	A chemical that can kill bacteria without harming a persons cells.
bacteria	a member of a large group of unicellular microorganisms that have cell walls but lack organelles and an organized nucleus, including some that can cause disease.
nucleus	The dense area in a eukaryotic cell that contains nucleic acids, the chemical instructions that direct the cell's activities.
host	An organism that provides a source of energy or a suitable environment for a virus or for another organism to live.
virus	A small, nonliving particle that particle that invades and then reproduces inside a living cell.
infectious disease	An illness that can pass from one organism to another.
autotroph	An organism that makes its own food.
heterotroph	An organism that cannot make its own food.
asexual reproduction	One parent needed.
sexual reproduction	Two parents needed.
binary fission	A form of asexual reproduction in which one cell divides to form two identical cells.
conjugation	The process in which a unicellular organism transfers some of its genetic material to another unicellular organism.
