Six Kingdoms

Eubacteria

Escherichia Coli

Escherichia coli also known as E. coli is often found in the environment as well as in the intestines of people and animals. E. coli is mostly harmless however some strains can cause illness.

Cyanobacteria

Cyanobacteria is a photosynthetic bacteria that can be found in all types of water.

These both classify as Eubacteria because of certain characteristics such as being a single cell, prokaryotic organism, having a circular DNA and containing peptidoglycan cell walls.

Archaebacteria

Crenarchaeota

Crenarchaeota are extremely heat tolerant and have been found living in hot springs and near deep sea vents.

Euryarchaeota

Euryarchaeota are able to survive in salty habitats and are found in marshes, wetlands and inside the human gut.

These organism are archaebacteria because they are single-celled microorganisms that are prokaryotes, similar to eubacteria but have many other differences such as not containing peptidoglycan cell walls.

Protista

Algae

Algae is a photosynthetic organism that often grows in or near water. They can be both unicellular or multicellular.

Amoeba

Amoeba’s have no fixed structures and can be found in bodies of warm freshwater. They are also unicellular.

These organisms are categorized as Protista because they are eukaryotic organisms that are not fungi, plants or animals.

Fungus

Yeast

Yeast is a unicellular organism that can convert it’s food into carbon dioxide and alcohol using fermentation.

Mold

Molds are multicellular organisms that will grow in damp places. It can cause health effects in some people however small amounts of exposure is not harmful.

Yeast and Mold have defining characteristics of fungi for example, they are heterotrophic (unable to make it’s own food) and must absorb nutrients from their surroundings, they are eukaryotic, and have cell walls containing chitin.

Plants

Poaceae

Poaceae, the grass family, has over 10000 species with a ride range from typical lawn grass to bamboo.

Cactaceae

Cactaceae, the cactus family, consists of about 1866 species and are mostly all adapted to dry environments.

Poaceae and Cactaceae are considered plants because of characteristics such as how they are multicellular eukaryotes, have organelles called chloroplasts, cell walls containing cellulose and root systems as well as many other defining characteristics.

Animal

Reptilia

Reptiles account for over 8700 species of air-breathing vertebrates that have scales, internal fertilization and amniotic development.

Mammalia

Mammalia are any vertebrate animals with mammary glands. This family consists of over 6000 different species.

Mammalia and Reptilia are part of the Animalia kingdom because of characteristics such as being a multicellular eukaryotic organism, heterotrophic and having no cell wall.
