LESSON 2: D2 - Introduction to Taxonomy Flashcards
Taxonomy
The science of classifying living things
How did Linnaeus rank species?
In taxonomic ranks based on shared characteristics
What is the taxnomical system used for?
To classify ogrnaisims on Earth (Phylogenetic tree)
Are all speices tied back to one common ancestor?
Yes
What is a clade
A taxonomic group that includes a single ancestor and all of its descendents
What are the 6 kingdoms?(The three domains broken down futher are called kingdoms)
- Plants
-Animals
-Bacteria
-Protists
-Fungi
-Archea
Describe kingdom Plantee
- Autotrophs
- Plant cells
-Multicelluar
-Eukaryotic
-Cell wall composed of cellulose
Describe kingdom Animalia
- Eukaryotic
-Multicellular - No cell wall and chloroplast
-hetrotrophs
Describe kingdom Eubacteria
- Single celled
-Prokaryotic - Cell wall
-Some are autotrops and some are heterotrophs
Describe kingdom Archaeabacteria
- Prokaryotic
-Cell and cell membrane are unique
Describe kingdom Protista
-Eukaryotic
- Diverse cell structure
-Some have Cell walls and chloroplast
TRUE OR FLASE:
Out of all the 6 kingdoms, not all are made up of more then 1 clade
TRUE
Which kingdom is do not form 1 clade
Protists
Homogulas traits
Traits that stem from a common evolutionary ancestor
What do we call a group of organisims?
Taxa
What are the 3 Domains
Bacteria, Archea, Eukarya
What two domains are prokaryotes?
Bacteria and Archea
Which domain makes up all of the life forms?
Eukarya
What goes under Eukerya
Kingdoms
What is the first name called in Taxonomy
Genus
What is the second name in Taxonomy
Speices name
What is Phylogeny?
Finding evolutionary relationships among speices
Archea has been around for very long
TRUE
Bacteria and Archaea are very similar
FALSE
- Different cell walls
Fungi
-Decomposers
-eukaryotic
-Most are multi-celluar
-cell wall made of chitin
