Biological Classification A:Domains and Kingdoms Flashcards
Domains and Kingdoms
Cellular organization
- prokaryotic vs. eukaryotic cells
- multicellular vs. unicellular
- mode of nutrition
3 factors used to organize organisms into kingdoms
- number of cells
- type of cells
- nourishment (feeding type)
cell number
unicellular
made up of only 1 cell
cell number
multicellular
made up of more than 1 cell
cell type
prokaryotic
cells that are missing a nucleus
cell type
eukaryotic
and membrane bound organelles
THEY HAVE A NUCLEUS
organisms obtain and use materials (food and energy) to grow, develop, and reproduce.
feeding type
autotrophs
make their own food (plants)
feeding type
heterotophs
eat other things for food (ex. animals)
heterotrphcy can occur through
ingestion
internal digestion in animals
heterotrophcy can occur through
What are the three Domains?
Bacteria, Archaea, Eukarya
What kingdom(s) fall in the Bacteria domain?
Bacteria
What kingdom(s) fall in the Archaea domain?
Archaea
What kingdom(s) fall in the Eukarya domain?
Protista, Plantae, Fungi, Animalia
Fungi
cell walls made of chitin, they dedcompose dead organisms and absorb the nutrients, heterotrophs, eat by absorbtion, made up of eukaryotic cells, can be both unicellular and multicellular
plantae
multicellular, eukaryotic cells, non-moving autotrophs, cell walls made of cellulose, have chloroplast, photosynthesize
kingdom animalia
multicellular, eukaryotic cells, no cell walls, can move due to a nervous system, exist on land, air, and water, complex organ systems, ingest food, heterotrophs
kingdom protista
both unicellular and multicellular, eukaryotic cells, both heterotrophic and autotrophic, most live in aquatic environments
kingdom archaea
unicellular, prokaryotic, heterotrophic and autotrophic, “ancient bacteria”, live in extreme environments, have cell walls
kingdom bacteria
unicellular, prokaryotic, both heterotrophic and autotrophic, cell walls contain peptidoglycan, “common bacteria”, many are important decomposers
