Classification
Organisms are classified and placed into kingdoms based on
characteristics
This kingdom includes multicellular organisms that perform photosynthesis and have cell walls made of cellulose.
plantae
The simplest animals that cannot move and filter feed in water; they lack tissues and true organs.
Sponges
Warm-blooded animals with feathers and wings.
Birds
Animals are divided into these two categories.
Invertebrates and Vertebrates
The number of Kingdoms.
six
This kingdom contains mainly single-celled prokaryotes with peptidoglycan in their cell walls and is often called "true bacteria."
Eubacteria (Bacteria)
Animals with radial symmetry and many have an internal skeleton with spines (e.g., sea stars).
Echinoderms
Aquatic animals that breathe through gills and usually have scales.
Fish
The kingdom that must consume food (ingest or absorb) to obtain energy rather than producing it via photosynthesis.
Animalia
The number of Domains
Three
This kingdom includes organisms like amoebas and large single-celled algae — often the most complex single-celled organisms.
Protista
Soft-bodied animals with a muscular foot; many have shells (e.g., snails, clams).
Molluscs
Cold-blooded vertebrates that typically have scaly skin and lay shelled eggs on land.
Reptiles
E. Coli belongs to this Kingdom
Bacteria
This Domain contains extremophiles
Archaea
This kingdom contains decomposers that absorb nutrients from other organisms and have cell walls made of chitin.
Fungi
Animals with stinging tentacles and a simple body plan (examples: jellyfish, sea anemones).
Cnidarians
Vertebrates that can breathe through their skin at certain life stages and usually have aquatic larval forms.
Amphibians
A term used to describe organisms that can make their own food.
Producers
The kingdom that includes organisms that are multicellular, heterotrophic, and lack cell walls.
Animalia
Archaebacteria are commonly found in these types of environments (think high heat, high salt, or low oxygen).
Harsh environments (extreme environments)
Animals with an external skeleton and segmented bodies (examples: insects, crustaceans).
Arthropods
Warm-blooded vertebrates that produce milk for their young and usually have hair or fur.
Mammals
These two Kingdoms cantain organisms that lack a nucleus.
