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
Protista are classified by cell structures like cilia and flagella
Plants are classified by VASCULAR tissue & REPRODUCTIVE structures Life Cycle MOSS (and relatives) has NO vascular tissue. All other plant groups DO have vascular tissue
Ferns reproduce with SPORES, not seeds Life Cycle
CONES are male or female Life Cycle
ANGIOSPERMS are flowering plants Life Cycle
Animal Phyla • Porifera (sponges) • Cnidaria (jellyfish) • Platyhelminthes(flatworms) • Nematoda (roundworms) • Annelida (segmentedworms) • Mollusca (snails, clams, squid) • Arthropoda (insects, crabs) • Echinodermata (starfish) • Chordata (vertebrates)
Phylum Spongebobius: Porifera are heterotrophic cells that group together
Phylum Cnidaria: all members have stinging cells and one body opening
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 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)
How did this happen? • Write a story that explains these observations: • DDT is an insect poison invented in 1941. When it was sprayed on mosquitoes in Savannah in 1942, 99% of mosquitoes died. • When DDT was sprayed in Savannah in 1966, only 61% of the mosquitoes died. • DDT is no longer used to control mosquitoes in Savannah
