Domains and Kingdoms

Domain Bacteria

• Eubacteria – prokaryotic and cell walls contain peptidoglycan.

• Some are aerobic and some are anaerobic.

• Most are heterotrophic and some are autotrophic

• More abundant than any other organism

BACTERIAL COLONY THAT IS ANTIBIOTIC BACTERIAL COLONY THAT IS ANTIBIOTIC RESISTANTRESISTANT

Domain Archaea

• More closely related to eukaryotes

• Cell walls do not contain peptidoglycan

• Can be autotrophic or heterotrophic

• Live in extreme environments – hot springs, thermal vents, salty lakes.

• Membrane bound organelles – mitochondria, endoplasmic reticulum….

• Multicellular, unicellular, autotrophic, heterotrophic

• Includes the kingdoms – protista, fungi, plant, and animal

Kingdom ProtistaKingdom Protista

• Unicellular, colonial, multicellular, and don’t have internal organs

• Plant-like – algae• Animal-like –

protozoan• Fungi-like – molds,

mildews

Kingdom FungiKingdom Fungi

• Unicellular, multicellular, heterotrophic, can’t move about

• Cell wall is made of chitin

• Main role as decomposers

Kingdom PlantaeKingdom Plantae

• Multicellular• Cell wall made of

cellulose• Most contain

chloroplasts• Mostly autotrophic• Tissue organize into

organs

Kingdom AnamaliaKingdom Anamalia

• No cell walls• Heterotrophic,

multicellular• Tissue organizes into

complex organs

• Live in land, water, or in air
