The condition in which an organism’s internal environment is kept stable in spite of changes in the external environment
spontaneous generation
The mistaken idea that living things arise from nonliving sources
Any living thing
binomial nomenclature
The classification system in which each organism is given a unique two-part scientific name indicating its Genus and species
The scientific study of how living things are classified
A group of similar organisms that can mate and produce offspring
An organism that cannot make its own food and feeds on other organisms
An organism that can make its own food
Organisms that have a true nucleus (example: plants, animals, protists)
Organisms that do not have a nucleus (example: bacteria)
A tiny nonliving particle that enters and then reproduces inside a host living cell.
A eukaryotic organism that cannot be classified as a plant, animal, or fungus

a tiny unicellular organism that lives in water or as a parasite

A mostly multicellular organism that reproduces using spores and is a heterotrophic decomposer
Microbe / microorganism
An organism that is so small you need a microscope to see it.
binary fission
The process that bacteria use to reproduce by splitting in two.
Organisms that benefit from living with, on, or in a host.

path=disease gen= producer

something that makes you sick

Compare and Contrast Viruses and Bacteria

Viruses and Bacteria are both microscopic and can make you sick. Viruses are non-living and have no cellsBacteria are living and unicellular

Compare and Contrast Bacteria and Protists

Bacteria and Protists are both unicellular and both types of pathogens.Bacteria are prokaryotes (no nucleus) and Protists are eukaryotes (have a nucleus). Protists are also larger than bacteria.

Compare and contrast fungi and protists

Fungi and Protists are both pathogens and both eukaryotes (have a nucleus)Fungi are usually multicellular and protists are usually unicellular. Fungi reproduce with spores and protists usually reproduce through fission.

What type of infections are antibiotics useful for treating?

Antibiotics are helpful in treating infections caused by bacteria.

They are not effective treatments for viruses, fungi, or protists.

What two parts make up a scientific name?

Genus then species

List the 4 types of pathogens we discussed in order from smallest to largest

1. Viruses

2. Bacteria

3. Protists

4. Fungi

Are organisms in the same kingdom, class, or genus level of taxa more similar/closely related?

Species contain the most similar organisms, but Genus are the next most closely related.
