Classification of Living Things
• Living species are placed into groups based on their observed characteristics.
• They are usually NOT placed into groups based on their habitat, their behavior, or their common names.
6 Kingdoms of Living Things
• Archaebacteria
• Eubacteria
• Protista
• Fungi
• Plantae
• Animalia
Bacteria are classified by SHAPE and BIOCHEMICALS
Animal-like Protista are classified by cell structures like cilia and flagella
Protista includesseveral types of Algae and Seaweed
classified based on chemical criteria (PS pigments)
Fungi are classified by how they make SPORES
Time Lapse
Life Cycle
Plants are classified by VASCULAR tissue & REPRODUCTIVE structures
MOSS (and relatives) has NO vascular tissue.
All other plant groups DO have vascular tissue

Animal Phyla
• Porifera (sponges)
• Cnidaria (jellyfish)
• Platyhelminthes (flatworms)
• Nematoda (roundworms)
• Annelida (segmentedworms)• Mollusca (snails, clams, squid)
• Arthropoda (insects, crabs)
• Echinodermata (starfish)
• Chordata (vertebrates)
Phylum Porifera: the Sponges
Phylum Spongebobius:
Porifera are heterotrophic cells that group together
Phylum Cnidaria: all members have stinging cells and one body opening
Sponge Bob walking his jellyfish
Phylum Cnidaria: corals and jellyfish
Phylum Platyhelminthes….the flatworms
They all have one body opening and a HEAD
(CEPHALIZATION)
Phylum Nematoda: the roundworms
All members of this group have TWO body openings
Phylum Annelida: the segmented worms
Phylum Mollusca:
All have a MANTLE which can produce “shell”
Phylum Arthropoda:
All have an exoskeleton made of protein
Phylum Echinodermata: Starfish and relatives
All have spiny skin and TUBE FEET
Phylum Chordata
All have:
Dorsal nerve cord
Pharyngeal gill structures
MOST have a backbone (vertebrae)
Phylum Chordata with no backbone
Phylum Chordata: Class Chondrichthyes
Phylum Chordata: Class Osteichthyes
Phylum Chordata, Class Amphibia
Phylum Chordata, Class Reptilia
Phylum Chordata, Class Reptilia
Phylum Chordata, Class Aves
