functions of modern systems of classification:
Group organisms according to their basic characteristics.
Give each organism a unique name.

Kingdom, Phylum, Class,
Order, Family, Genus, and Species. New books list 8 Starting with Domain
Bacteria, Archaea, and Eukarya

Second largest group. Plural Phyla,
each Phylum is made up of several
Made up of
Name consists of Genus and species
ex. Wolf is Canis lupus
five kingdom systems of classification: Plants, Animals, Protists, Monerans,
- Eukaryote Autotrophs (Make their own food) Most are multicellular and most
- Eukaryote Heterotrophs (Can=s
make their own food) All are multicellular, and have tissues, most have organs.
- Eukaryote Most unicellular organisms with nuclei.
Fungi - Eukaryote Plant-like, however do not contain chlorophyll or make their own food. (Molds and Mushrooms).
Monerans - Prokaryote Unicellular organisms without a nucleus. (All bacteria and blue green algae).
six kingdom classification system divides Moneran in to two different Kingdoms
Eubacteria and Archaea
