Taxonomy: The Science of Classifying Organisms
Hello. Today we took notes on taxonomy. We had to listen to a presentation and take the notes. Now I'll put them up on the website. I'll see you later. Peace!
Naming & Organizing are part of the same process:
Grouping:
More on Naming:
What is a species?
> Defined as organisms that can be interbreed with one another and can produce fertile offspring. When 2 organisms of different species interbreed, the offspring is called a hybrid.
Classification into a kingdom is based on certain criteria:
- The system was developed by Carolus Linnaeus who used Greek and Latin names for organisms
- He also created a system where we place all organisms into few large groups
Grouping:
- Kingdom
- Phylum
- Class
- Order
- Family
- Genus
- Species
More on Naming:
- The system of naming is called BIONOMIAL NOMENCLATURE - which means it's a 2-name system
- Must be either underlined or italicized
- Genus is capitalized, species is lowercased
- Can be abbreviated, Ex: F. leo & F. tigris
What is a species?
> Defined as organisms that can be interbreed with one another and can produce fertile offspring. When 2 organisms of different species interbreed, the offspring is called a hybrid.
Classification into a kingdom is based on certain criteria:
- The number of cells (unicellular/ multicellular)
- How it obtains energy (heterotroph/ autotroph)
- Type of cell (eukaryotes/ prokaryotes)
Kingdom Animalia
|
Kingdom Plantae
|
Kingdom Fungae
|
Kingdom Protista
|
Kingdom Eubacteria & Archaebacteria
|
3 Domain System
Domain Eukarya - includes organisms composed of eukaryotic cells (plants, animals, fungi, protists)
Domain Archaea - includes only "ancient" bacteria, Archae-bacteria
Domain Bacteria - includes all prokaryotic cells, Kingdom Eubacteria
I see that you are done. I'll see you later. Peace!
