1. Virus Host Parasite Vaccine Bacteriophage
A tiny non living particle that invades and then reproduces itself inside of a living cell
Host
The organism that a parasite or virus lives on or in
Parasite
The organism that benefits by living on or in a host in a parasitic relationship
Bacteriophage

2. Bacteria Flagellum Binary Fission Asexual Reproduction
Single celled organism that lack a nucleus
Flagellum
A long whip like structure that helps a cell move
Binary Fission
A form of asexual reproduction in which one cell divides to form two identical cells
Asexual Reproduction
A reproductive process that involves only one parent and produces offspring that are identical to the parent
Sexual Reproduction
A reproductive process that involves two parents that combine their genetic material to produce a new organism that differs form the parents

3. Conjugation Endospore Decomposer Protist Pasteurization
The process in which a unicellular organism transfers some of its genetic material another unicellular organism
Endospore
A small rounded thick walled resting cell that forms inside of a bacterial cell
Pasteurization
A process of heating foo to a temperature that is high enough to kill most harmful bacterial without changing the food’s taste
Decomposer
An organism that breaks down chemicals from wastes and dead organisms returning important materials to soil and water
Protist
A eukaryotic organism that cannot be classified as a plant animal or fungus

4. Protozoan Pseudopod Contractile Vacuole Cilia Symbiosis
An animal like protist
Pseudopod
A false foot or temporary bulge of cytoplasm used for feeding and movement in some protozoans
Contractile Vacuole
The cell structure that collects extra water from the cytoplasm and then expels it from the cell
Cilia
The hair like projections on the outside of cells that move in a wave like manner
Symbiosis
A close relationship between two organisms of different species that benefits at least one of the organisms

5. A tiny cell that is able to grow into a new organism
Mutualism
A close relationship between organisms of two different species where both organisms benefit
Algae
Plant like protists
Spore
A tiny cell that is able to grow into a new organism
Fungus
A eukaryotic organism that has cell wails, spores to reproduce and is a heterotroph that absorbs its food
Hyphae
The branching thread like tubes that make up the bodies of multicellular fungi

6. Fruiting Body Budding Lichen
The reproductive structure of a fungus that contains many hyphae and produces spores
Budding
A form of asexual reproduction of yeast in which a new cell grows out of the body of the parent
Lichen
The combination of a fungus and either an alga or an autotrophic bacteria that live together in a mutualistic relationship
