The Six KingdomsWhen Linnaeus developed his system ofclassification, there were only two kingdoms,Plants and Animals. But the use of themicroscope led to the discovery of neworganisms and the identification of differences incells. A twokingdom system was no longeruseful. Today the system of classification includes sixkingdoms.
The Six Kingdoms:Plants, Animals, Protists, Fungi,Archaebacteria, Eubacteria.

PlantsYou are probably quite familiar with the membersof this kingdom as it contains all the plants thatyou have come to know flowering plants,
In addition plants are autotrophs,organisms that make their own food.

mosses, and ferns. Plants are all multicellularand consist of complex cells.
With over 250,000 species, the plant kingdom isthe second largest kingdom. Plant species rangefrom the tiny green mosses to giant trees.
Without plants, life on Earth wouldnot exist! Plants feed almost all theheterotrophs (organisms that eatother organisms) on Earth. Wow!
AnimalsThe animal kingdom is the largest kingdom withover 1 million known species.
All animals consist of many complex

cells. They are also heterotrophs. Members of the animal kingdom arefound in the most diverseenvironments in the world.
ArchaebacteriaIn 1983, scientists tool samples from a spot deepin the Pacific Ocean where hot gases and moltenrock boiled into the ocean form the Earth’sinterior. To their surprise they discoveredunicellular (one cell) organisms in the samples.These organisms are today classified in thekingdom, Archaebacteria.
Finding Archaebacteria: The hotsprings of Yellowstone NationalPark, USA, were among the firstplaces Archaebacteria were

Archaebacteria are found in extremeenvironments such as hot boiling waterand thermal vents under conditions withno oxygen or highly acid environments.
discovered. The biologists picturedabove are immersing microscopeslides in the boiling pool onto whichsome archaebacteria might becaptured for study.
EubacteriaLike archaebacteria, eubacteria are complex andsingle celled. Most bacteria are in theEUBACTERIA kingdom. They are the kindsfound everywhere and are the ones people aremost familiar with.
Eubacteria are classified in their own kingdom Most eubacteria are helpful. Someproduce vitamins and foods like yogurt.

because their chemical makeup is different. However, these eubacteria, Streptococcipictured above, can give you strepthroat!
FungiMushrooms, mold and mildew are all examples oforganisms in the kingdom fungi. Most fungi are multicellular and consists ofmany complex cells. Fun Facts about Fungi
Some fungi taste great and others can kill you!
Fungi are organisms that biologistsonce confused with plants, however,unlike plants, fungi cannot maketheir own food. Most obtain theirfood from parts of plants that aredecaying in the soil.
ProtistsSlime molds and algae are protists.

Sometimes they are called the odds and endskingdom because its members are so differentfrom one another. Protists include allmicroscopic organisms that are not bacteria, notanimals, not plants and not fungi.
Most protists are unicellular. You may bewondering why those protists are not classified inthe Archaebacteria or Eubacteria kingdoms. It is because, unlike bacteria, protists are complexcells.
These delicate looking diatoms areclassified in the protist kingdom.
