| Question | Answer |
|---|---|
| Organisms | living things |
| Unicellular | single celled organisms, including bacteria |
| Multicellular | organisms that are composed of many cells |
| Levels of classification | kingdom phylum class order family genus species |
| Homeostasis | the maintenance of stable internal conditions |
| Autotrophs | organisms that make their own food |
| Heterotrophs | organisms that cannot make their own food |
| taxonomy | the scientific study of how things are classified |
| binomial nomenclature | the naming system of two parts that Linnaeus used in which 1st look at observable features, then put in groups, then based on observations, give each a two part name |
| virus | a tiny nonviving organism that gets into and reproduces inside a cell |
| host | an organism that provides a source of energy for a virus or another organism |
| parasite | an organism that lives on a host and causes it harm |
| bacteriophage | a virus that infects bacteria |
| flagella | a long whip that helps cells to move |
| binary fission | 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 who combine their genetic material to produce a new organism, which differs from both parents. |
| Conjugation | a process in which one bacterium transfers some genetic material into another bacterium through a thin, threadlike bridge that joins the two cells. After the transfer, the cells separate |
| Endospore | a small, rounded, thick resting cell that forms inside a bacteria cell + survives through harsh conditions |
| infectious disease | illnesses that pass from one organism to another |
| antibiotic resistance | when bacteria are able to survive in the presence of an antibiotic |
| Prokaryote | organisms whose cells lack a nucleus |
| Nucleus | a dense area inside a cell that contains nucleic acids |
| Eukaryote | organisms with cells that contain nuclei |
| protists | eukaryotes who live in moist surrounding and don’t fit into other classification groups |
| protozoans | animal like protists that are unicellular |
| pseudopods | "false foot" inable sarcodines, protazoans, to move |
| Cilia | hairlike projections from cells that move with a wavelike motion |
| Symbiosis | a close relationship in which at least one of the species benefits |
| Algae | plantlike protists that are autotrophs and very diverse |
| Algal bloom | the rapid growth if a population of algae |
| Hyphae | the branching, thread |
| Fruiting body | the spores produced by fungi in reproductive bodies |
| Budding | the reproductive process in which a small yeast cell grows from the body of a parent cell |
| Fungi | eukaryotes that have cell walls, are heterotrophs that feed by absorbing their food, and use spores to reproduce |
| infectious agents | bacteria, virus, protazoan, helminth, fungus, proin |
| cytoplasm | the region inside the cell membrane that contains a gel-like material |
| animal-like protists | protazoan, unlike animals |
| plant-like protists | algae |
| protists | eukaryotes that cannot be classified as animals, plants, or fungi |
| proin spread through | food |
| bacteria spread through | direct or indirect contact, food, water, air, animals |
| virus spread through | direct or indirect contact, food, water, air, animals |
| prion spread through | food |
| proatazoa spread through | food, water, animals |
| heminth spread through | direct or indirect contact, food, water, air |
| fungus spread through | direct or indirect contact, water, air, animals |
| plant-like protists | Plant-like protists (algae): diatoms, euglena, red algae, green algae, brown algae |
| Fungus-like protists: | Slime molds Water molds Downy molds |
| Animal-like protists | amoeba, Paramecium |
| Viral infections | AIDS Common Cold Influenza Chicken Pox Mononucleosis |
| bacteria infections | TSS Strep Throat Ear Infection Salmonella Impetigo Pink Eye |
