Classification System
2
How are organisms classified TODAY?
All living things are classified into one of three domains: Bacteria Archaea Eukarya
3
Bacteria These organisms have 3 basic characteristics:
They are unicellular. They are prokaryotic. They live everywhere around us: On the things we touch In the air In our skin
4
Archaea These organisms have 3 basic characteristics:
They are unicellular. They are prokaryotic. They live in Earth’s most extreme environments: Underwater volcanoes Geysers Hot springs
5
Archaea These environments are too extreme for any other organism on Earth because they’re: Too hot Too acid or alkaline
6
So, how are bacteria and archaea similar but different?
Unicellular Microscopic Prokaryotes Different Structure Chemical makeup Habitat
7
Eukarya Organisms in this domain have only 1 thing in common:
They are eukaryotes
8
Eukarya Protists Fungi Plants Animals
There are 4 types of eukaryotic organisms (also known as kingdoms) Protists Fungi Plants Animals
9
Fungi These organisms have 3 basic characteristics:
They’re heterotrophs Most of them feed from dead organisms They’re multicellular Only few fungi species are unicellular They’re eukaryotes Mushrooms Mold Mildew
10
Plants These organisms have 3 basic characteristics:
They’re autotrophs They produce their own food through photosynthesis They’re multicellular They’re eukaryotes Flowering plants Moss Trees
11
Animals These organisms have 3 basic characteristics:
They’re heterotrophs They’re multicellular They’re eukaryotes They move Sea stars Insects Vertebrates
12
Protists These organisms have only 2 things in common:
They’re heterotrophs They can’t be classified as plants, animals or fungi. Seaweed Amoeba Slime mold
13
So now you know it! This is what our modern classification system looks like: Kingdoms Domains Living Things Bacteria Archaea Eukarya Protists Fungi Plants Animals
