KINGDOMS OF ORGANISMS Introduction
Kingdoms • All organisms can be divided into kingdoms of organisms • Organisms are placed into kingdoms based on 3 characteristics: • Type of cell • Form of nutrition • Number of cells
Type of Cell • Prokaryotic—cells lack a nucleus and organelles • Eukaryotic—cells have a nucleus and organelles
Form of Nutrition • Autotrophic—these organisms make their own food • Heterotrophic—these organisms can not make their own food
Number of Cells • Unicellular—these organisms have only one cell • Multicellular—these organisms have more than one cell
6 Kingdom System • Kingdom Archaebacteria • Kingdom Eubacteria • Kingdom Protista • Kingdom Fungi • Kingdom Plantae • Kingdom Animalia
Kingdom Archaebacteria • Prokaryotic cells • Most have cell walls, but some don’t • Unicellular • Some are autotrophic and some are heterotrophic • Contains the bacteria that live in harsh environments like hot springs, volcanic vents or highly salty water; they live where no other organisms can survive
Kingdom Eubacteria • Contains all the other bacteria that are not in the Kingdom Archaebacteria • Prokaryotic cells • Most have cell walls, but some don’t • Unicellular • Some are autotrophic and some are heterotrophic • Some are considered “good” and some are “bad”
Kingdom Protista • Eukaryotic • Some have cell walls, but some don’t • Contain uni- and multicellular organisms • Some are autotrophic and some are heterotrophic • Only characteristic they have in common is they are all eukaryotic
Kingdom Fungi • Contains mushrooms, yeast, mold and mildew • Eukaryotic • Have cell walls made of chitin • Yeast are unicellular; all others are multicellular • Heterotrophic – absorptive
Kingdom Plantae • Includes all the plants • Eukaryotic • Have cell walls made of cellulose • Multicellular • Autotrophic • Contain chloroplasts
Kingdom Animalia • Eukaryotic • No cell walls • Multicellular • Heterotrophic • Only Kingdom with NO cell walls
