- name the 6 kingdoms
- Archaebacteria, Eubacteria, Protista, Fungi, Plantae, Animalia
- Name the three shapes of bacteria
-
Basillus- rod shaped
Cocus- spherical
Sprillum-spiral - Invertebrates with bilateral symmetry
- Arthropods, annelids, mollusks
- Invertebrate animal phyla that have radial symmetry
- Echinoderms, Cnidarians
- Invertebrates wiht a gastrovascular cavity
- poriferia, cnidarians,
- Kingdom Archaebacteria
- evolved first; most primitive
- Kingdom Eubacteria
- Common bacteria; both beneficial and harmful to humans; three general shapes;
- Protists
-
diverse eukaryotivc mostly unicellular
freshwater or amrine
three forms of movement:
flagellum-whiplike tail
cilia-hairlike projections
Pseudopodia- extended cytoplasm
Three types: animal like (protoaoza
plant like (algae)
fungus like (slimes and water molds) -

towards the middle (center) - Animal characteristics
-
complex, multicellular, heterotroplic, eukaryote
specialization
movement
symmetry- bilateral or radial
cephalization
vertebrates/invertabrates
sexual reproduction - Phylum Porifera
-
Sponges
aquatic, pore-bearing
no true tissue/organs
no symmetry
can reproduce sexually or asexually-hermaphroditic
Sissil: attach don't move
filter feeders - Phylum Cnidarian
-
Animals with stinging cells and tentecles
radial symmetry
have tissues and few simple organs
2 cell layers
Gastrovascular cavity
Specialized cells for defense and prey
Nerve net
Two body plans- polyp, and Medusa - Phylum Platyhelminths
-
Flatworms
free-living or parasitic
bilateral symmetry
Gastrovascular cavity
Primitive organs
Gas exchange w/en. thru diffusion
cephalization
planarian - Phylum Nematoda
-
Roundworms
Digestive tract w/ 2 openings
Trichinella in undercooked pork - Phylum Mollusca
-
Mollusks
Mostl bilateral symmetry
Radula
Three classes:
Gastropoda: most have shell
open circulatory
Bivalvia: unique opening and closing shell-no head
Cephlaupod- free swimming; closed circulatory; chromaphores - Phylum Annelid
-
segmented worms
Advantages: segemented coelom enables different parts of the body to contract and expand independently
Cephalization
CLOSED circulatory system
well developed digestive circulatory and nervous and respiratory systems - Phylum Arthropoda
-
Arthropoids- segmented and jointed feet
hard exoskeleton for protectiona nd support
bilateral symmerty
OPEN circulatory system
breathe thru spericals
compound eyes - Phylum Echinodermata
-
spiny skinned animals
(penta) radial symmerty
NO cephalization
endoskeleton made of calcium carbonate plates
water vascular system
tube feet
External fertilization - Class Agnatha
-
Jawless fish
descendents of first fish
no jaws, oaltes or scales
Cartilage skeleton, eel-like body - Class Chondrichthyes
-
Cartaliage fish
cartaliage skeleton
movable jaws
paired fins
carnivorous - Class Osteichthyes
-
Bony fish *fish most firmiliar with
bony skeleton
swim bladder to control byoyancy
Scales to protect and reduce water resistance - Class ASmphibia
-
moved onto land to escape preditors and take advantage of new rescources
aquatic larvae terrestrial adult
moist thin skin w/o scales
webbed feet w/o claws
breathe w/gills lungs and skin - Class Reptilia
-
50 mya
AMNIOTIC EGG- embryo encased in self contained aquatic enviornment
scales made of keratine
prevent water loss
have lungs
cold-blooded - Class Aves
-
140 mya birds
wings, feathers, no teeth
lightweight skeleton make of fused skeletal parts
large sternum
extremely efficiant respritory system
body temp warmer than humans - Class Mamimalia
-
4 chambered heart
warm-blooded
hair/fur
produce milk for young
single jaw bond, specialized teeth
appeared during time of dinosaurs
Three types:
Monotremes-lay eggs
Marsupials-born early and develop in mother's pouch
Plavental- complete development in womb
