How are organisms classified into domains or kingdoms?
Organisms are classified into domains and kingdoms based on their cell type, their ability to make food, and the number of cells in their bodies.
What are the 3 domains of life?
1. Bacteria
2. Archaea
3. Eukarya
What are 2 domains of Bacteria?
Autotrophs and hetertroph
What is an autotroph?
an organism that can make its own food. Ability to make food.
auto- self
troph-feeder
What is a heteotroph?
An organism that cannot make its own food.
What are bacteria?
Prokaryotes
Cell type and how many cells
What is a prokaryotes?
a unicellular organisms whose cells lack a nucleus.
What is in the Domain Archaea? Why is it unique?
the organisms in this domain live in conditions where other organisms would die, such as salty water, gaseous conditions, and very hot water.
What are some Archaea?
autotrophs and heterotrophs
Archaea
they are unicellular prokaryotes
In the domain Eukarya?
all eukarya are eukaryotes
What are eukaryotes?
organisms with cells that contain a nucleus.
What are the 4 kingdoms in the domain Eukarya?
1. protists
2. fungi
3. plants
4. animals
What are protists?
any eukaryotic organism that cannot be classified as a fungus, plant, or animal
"odds+ends" kingdom
Example: seaweed
What is fungi?
multicellular eukaryotic organisms, except yeast which is unicellular.
What are plants?
great variety of organisms including giant red wood trees to small mosses.
What are animals?
great variety of organisms.
What is classification?
putting things in groups by similarities
What is taxonomy?
the scientific study of how organisms are classified.
Why do biologists classify organisms?
Biologists use classification or organize living things into groups so that the organisms are easier to study.
What is binomial nomenclature?
the naming system for organisms. It is a two part naming system. The 2 parts are called genus and species.
What is genus?
A classification grouping of closely related organisms. It is the first part of an organisms scientific name.
What is species?
A group of similar organisms that can mate with each other and produce off spring that can also mate and reproduce.
What is an example of Species?
Felis domesticus

genus species
What is binomial nomenclature format?
-italics
-first letter of the first word should be a capital
ex. Felis domesticus
What are the levels of classification?
Domain
Kingdom
Phylum
