TAXONOMY terms

Taxonomy

the study of classifying living things

name all taxonomy classifictions in order

Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species

Domain classification

by cell type/structure

Kingdom classification

by shared characteristics

Ingestive/Absorvative

ING: digests food (meat, etc.)

AB: absorbs food (light, etc.)

Multicelluar/Unicelluar

MULTI: having multiple cells (that can be seen with the naked eye) (EX: plants, animals)

UNI: having one cell (needing to be seen with a microscope)

Filamentous

a formaiton of unicelluar organisms in a line

Unnicelluar (formation)

a formaiton of only one unicelluar organism

Colonial/Colony

a formation of a group of unicelluar organisms in a cluster

Autotroph/Heterotroph

AUTO: making it’s own food (EX: photosynthesis)

HETERO: finding it’s own food (EX: hunting)

Eukaryotic/Prokaryotic

EU: having a membrane-bound nucleus + organelles

PRO: having no nucleus, organelles, or membrane

Motile

able to move

extremophile 

a microorganism living in conditions having extreme temperatures, acidity, alkanlinity, and/or chemical concentration

Kingdom classificaitons:

Animal, Plants, Fungi, Protist, Bacteria, Archaea

Human classificaiton name:

Homo Sapiens

Nethanderal classificaiton name:

Homo Neandrithalis

Bionomial Nomoclature

naming organisms with two words to better classify/understand them

1st WORD: Genus

2nd WORD: Species

why is bionomial nomoclature used? 

• creates a clear communication for scientists around the world

• eliminates confusion 

• eliminates language barriers

• gives every known organism a unique + globally recognized name

Animals

Eukaryotic, Multicelluar, Ingestive, Heterotroph, Motile (—> no cell walls)

Plants

Eukaryotic, Multicelluar, Absorvative, Autotroph

Fungi

Eukaryotic, Multicelluar, Absorvative, Heterotroph

Protist

Eukaryotic, Uni/Multicelluar, Ingestive/Absorvative, Autotroph/Heterotroph, motile

Bacteria

Prokaryotic, Unicelluar, Ingestive/Absorvative, Autotroph/Heterotroph,

Archaea

Prokaryotic, Unicelluar, Ingestive/Absorvative, Autotroph/Heterotroph,

difference between plants and fungi

composition of cell walls

Plants: Cellulose

Fungi: Chitin

difference between bacteria and archaea

cell walls

Bacteria: containing Peptioglycans (that strengthen the cell wall)

Archaea: do not contain Peptioglycans + extremophiles
