Classifing

Classifying

arranging organisms into groups based on their similarities; makes life on earth easier to find, identify, and study

Levels of Classification from Largest to Smallest

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

Taxonomic Hierarchy

Levels of Classification

Prokaryote

No nucleus(ex. Bacteria/monera)

Eukaryote

Has a nucleus(ex. nearly every living thing but bacteria)

Autotroph/Producer

Makes food via photosynthesis (ex. plantae)

Heterotroph/Consumer

eats other organisms for food (ex. animals)

Decomposer

type of consumer-breaks down decaying things for nutrients (ex. fungi)

Binary Fission

type of asexual reproduction done only by bacteria

Six Kingdoms

Eubacteria, Archaebacteria, Protists, Fungi, Plants, Animals

Bacteria cells

Prokaryote, Unicellular

Bacteria’s Energy and Reproduction

Either, Binary Fission

Bacteria Characteristics

Helpful and harmful, reproduces quickly

Difference between Eubacteria and Archaebacteria

Archaebacteria can live in extreme environments

Protist cells

Eukaryote, mostly unicellular

Protist’s Energy and Reproduction

Either, mostly asexually

Protist Characteristics

Classified by how food is obtained, most diverse kingdom - with qualities of fungi, plants, and animals

Fungi’s Energy and Reproduction

Heterotrophs, Either

Fungi, Plant, and Animal cells

Eukaryote, Multicellular

Plants’ Energy and Reproduction

Autotroph, either

Animals’ Energy and Reproduction

Heterotroph, Sexually
