18-3 Two Modern Systems of Classification • kingdomcell typeno. of cellsnutrition • Archaebacteria pro. uni. both • Eubacteria pro. uni. both • Protista euk. both both • Fungi euk. both hetero. • Plantae euk. multi. auto. (some hetero) • Animalia euk. multi. hetero.
Prokaryotic = pro. • Eukaryotic = euk. • Unicellular = uni. • Multicellular = multi. • Heterotrophy = hetero. • Autotrophy = auto.
1. Kingdom Archaebacteria ·“Ancient bacteria” chemosynthetic bacteria. · Live in harsh environments: sulfurous hot springs, very salty lakes, intestines of mammals. ·Resembles first kinds of organisms to live on Earth.
2. Kingdom Eubacteria ·“True bacteria” use oxygen. ·Do not live in harsh environments. ·Cause tooth decay, milk to turn into yogurt, food poisoning, other disease causing bacteria. • Along with kingdom archaebacteria, these include greatest number of living things on Earth.
3. Kingdom Protista ·Mostly unicellular ·Giant kelp is multicellular but it lacks specialized tissues (which plants have) ·50,000 species • euglena, amoeba, paramecium and algae
4. Kingdom Fungi ·Absorb nutrients (do not ingest) ·100,000 species ·mushrooms, puffballs, molds, mildews, rusts and smuts
5. Kingdom Plantae ·Most photosynthesize ·Most on land ·350,000 species • mosses, ferns, conifers and flowering plants
6. Kingdom Animalia ·Symmetrical body organization ·Move about their environment • Humans, insects, reptiles, amphibians, birds
3-Domain System • Used in modern science. Based on differences of RNA. • DomainKingdom • Bacteria Eubacteria • Archaea Archaebacteria • Eukarya Protists Fungi Plantae Animalia
