biodiversity and taxonomy Flashcards
1
Q
what are the domains of life
A
- bacteria
- archaea
- eukarya
2
Q
what type of cells do the domains of life belong to?
A
- prokaryotic cells: bacteria, archaea
- eukaryotic cells: eukarya
3
Q
name the kingdoms
A
- eubateria
- archaebacteria
- protists
- plantae
- fungi
- animalia
4
Q
organisms are placed into their kingdoms based on…
A
- cell type: complex or simple
- ability to make food
- number of cells in their body
5
Q
eubacteria
A
- single-celled, prokaryotic
- bacteria you are probably most familiar with
- most are beneficial (some produce vitamins and foods like yogurt, but some (like Streptococci) can give you strep throat
6
Q
archaebacteria
A
- single celled, prokaryotic
- extremophiles (can exist in extreme settings, such as temperature, thermal vents, acidity, no oxygen, boiling water, etc)
7
Q
animalia
A
- largest kingdom, abt. 1.5 million species
- multicellular and eukaryotic
- heterotrophs
8
Q
plantae/plants
A
- second largest kingdom (400,000 species)
- multicellular, eukaryotic
- autotrophs
9
Q
fungi
A
- most multicellular (except yeast), all eukaryotic
- cannot produce its own food
- obtain food from decaying plants in soil
- abt. 155,000 species
10
Q
protists
A
- most unicellular, all eukaryotic
- all microscopic organisms that do not fall under the others are protists
- organisms in this kingdom are all very different from each other
11
Q
difference between prokaryotic and eukaryotic cells
A
eukaryotic cells have nucleuses
12
Q
what falls under each domain?
A
archaea: archaebacteria
bacteria: eubacteria
eukarya: protista, fungi, plants, animals
13
Q
eubacteria have a cell wall made of ___
A
peptidoglycan
14
Q
taxonomy
A
the science of naming organisms and assigning them to groups
15
Q
name the taxonomic levels
A
domain, kingdom, phyllum, class, order, family, genus, species
