Diversity of Living Things

Archaebacteria

similar to bacteria, cell wall without peptodyglocan

Psychrophiles

cold environments

Thermoacidophiles

extreme salt environments

Halophiles

thrive in high salt concentrations

Methanogens

no oxygen environments

Eubacteria

rigid cell walls wot peptidyglocan and flagella for movement

Spiral

Spirillum

has a twisted shape

Spherical

Streptococcus

remains in chains after dividing

Rod shaped

E. Coli

found in lower intestine of warm blooded organisms

Prokaryotes

small, simple, commonly know as bacteria

Unicellular

Animals

pollinators help spread seeds

Mollusca

Foot for movement, bigger organs and mantle for protection (Shell)

snail

Echinoderms

Radial symmetry and nerves extend everywhere (they don't have a real head and body is made up of tightly interweaved muscles)

star fish

Arthopoda

Have joint limbs unlike Echino. and other phylums + internal airways

Spider

Hexapoda

insects or incecta

Crustacea

branchipoda

Myriapoda

symphyla

pauropoda

diplopoda

millipede

chilopoda

centipede

Chelicerata

Chordata

Subphyla =

Vertebrata

Superclass =

Tetrapods

Mammilia

Mammary glands – produce milk for young -Body hair ( = insulation, camoflague, waterproofing, defense) -Endothermic, four-chambered hearts, highly developed brains -Specialized teeth

lion

Amphibia

-Gas exchange across moist skin -External fertilization in water -Adults live on land, but require moist environment

frog

Urochordata

Cephalochordata

Monkey

Mammals

monotremes

lay eggs

monotremata

platypus

marsupials

live birth

Diprotodontia

kangaroo

placentals

born from mothers uterus attached to placenta

Magnorder Xenarthra

sloths

Nematoda

roundworms and 2 openings in digestive system compared to 1 in Platy.

pin worms

Platyhelminthes

simplest organism in which organs occur -MILESTONE: can also reproduce asexually

tape worm

Cnidaria

they develop nerves and sting/paralyze prey rather than using

jelly fish

developed stinging tentacles

Porifera

sea sponge

Protista

cell wall, uni or multicellular

Feeding strategies

Decompose

Decayed matter

Fungus like

Water moulds

Peronosporales

Slime moulds

Protostelids

Photosynthesis

Sunlight

Plant like

Dinoflagellates

Dinophyceae

Diatoms

Pennate

Green Algea

Marino

Brown Algae

Kelp

Heterotrophs

Feed on other organisms

Animal like

Ciliates

Paramecia

Cilia help swim and capture food

Flagellates

sperms

Flagella-tail like

Sarcodines

Amoeba

Pseudopods

Sporozoans

Glardia

no movement

Plants

Eukaryotes

bigger and more complicated

Multicellular

Fungi

Multicellular, heterotrph

Basidiomycota

Jelly fungi

clublike-mass of hyphae to absorb water,Cap-produce spores

Ascomycota

Mildews,yeast

Saclike structures (ascus), prodce two kind of spores(conidia)

Zygomycota

Black Bread Mold

Black spots(sporangia), release spores

Chytridiomycota

Algea

Large pores, produce flagellated spores
