Six Kingdoms of Life

Classification into a Kingdom is based on certain criteria… 1. Number of Cells (Uni-cellular or Multi-cellular) How it obtains ENERGY (Autotroph or Heterotroph) Type of Cell (Eukaryotic or Prokaryotic)

Number of Cells Unicellular: Made of ONE cell Multicellular: Made of MANY cells

How it obtains ENERGY Autotroph: Makes it own food for energy Heterotroph: Consumes food for energy

Type of Cell Prokaryote: DNA is free flowing in the cell (NO NUCLEUS) Eukaryote: DNA is packaged in a membrane bound Nucleus

Six Kingdoms Archaebacteria (prokaryotes) Eubacteria (prokaryotes) Protists Fungi Plants Animals

Kingdom Archaebacteria Oldest form of life ARCHAE = Ancient bacteria Unicellular (Single cell organism) Prokaryotes (do not have a nucleus) Can be Autotrophs or Heterotrophs

Archaebacteria Found in extreme harsh environments *Geysers *Hotsprings *Volcanic ocean vents

Kingdom Eubacteria Second oldest form of life Eu = True bacteria Unicellular (Single cell organism) Prokaryote (do not have a nucleus) Autotroph or Heterotroph

Eubacteria Most familiar/common bacteria *Streptococcus *Lactobacillus *Staphylococcus

Kingdom Protista “Odds and Ends” kingdom All microscopic organisms that are not plants, not animal, not bacteria, and not fungi. Unicellular (Single cell organism) Heterotroph or Autotroph Eukaryote (have a nucleus)

Protista Most live in water! EX: Algae, Amoeba, Paramecium, Euglena

Kingdom Fungae Most are Multi-cellular organisms Heterotrophic (mainly decomposers) Eukaryote (Have a nucleus)

Fungae Mold Mildew Mushrooms Some cause diseases *ringworm *athlete’s foot

Kingdom Plantae Second largest kingdom Multi-cellular organisms Autotrophs *Producers (make their own food) Without plants life as we know it would not exist. Eukaryotic

Kingdom Plantae

Kingdom Animalia Multicellular Heterotrophic (Consumer – Must eat for energy) Eukaryotic

Kingdom Animalia

Three Domain System  Recently, scientists have added a group above Kingdom.  Three groups, called DOMAINS, contain each of the six kingdoms. Domain Eukarya - includes organisms composed of eukaryotic cells (plants, animals, fungi, protists) Domain Bacteria - includes all prokaryotic cells, Kingdom Eubacteria Domain Archaea - includes only "ancient" bacteria, Archaebacteria
