Kingdoms

Kingdom Protista

all eukaryotes
most single-celled, some primitive multicelled organisms
heterotrophs: amoeba & paramecium and autotrophs: euglenas (red eye spot to find light and carry out photosynthesis)
move in different ways; amoebas use pseudopods, paramecium use cilia, euglena; flagella
seaweeds and slime molds
some carry out conjugation
some cause serious diseases such as amoebic dysentry and malari

Kingdom Fungi

all heterotrophic eukaryotes
uni or mulicellular
extracellular digestion: secreting hyrolytic enzymes outside the body, after digestion absorb nutrients by diffusion
important to ecosystem: decomposers
saprobes: obtain food from decaying organic matter; recycle organic matter
cell walls of chitin
certain ones combine with algae (mutal; symbiotic relationship) form various lichens photosynthtic and can survive harsh cold enviroments, often are the pioneer orgnaism, first to colonize a barren enviorment in an ecological sucession
asexaully by budding yeast, spore formation bread mold, fragmentation (single parent breaks into pieces and create whole new indiviuals)
sexually
i.e. yeast, mold, mushroom, fungus on athletes foot

Kingdom Plantae

mulitcell, nonmotile, autotrophic eukaryotes
cell wall made of cellulose
photosythesis by chlorphyll a and b
store carbs as starch
reproduce sexually; alternate between gameotphyte (n) and sporophyte (2n) generations
some have vascualar tissue (tracheophytes) some don't (byrophytes)
i.e. mosses, flowers, ferns, and cone-bearing

Kingdom Animalia

heterotrophic, multicell eukaryotes
most motile
reproduce sexually; dominant diploid stage (2n)
in most small flagellated sperm fertilizes nonmotile egg
classify by anatomical features (homo structures) and embryotic development
35 phyla, but only need to know 9: poriefa, cnidarians, platyhelminthes, nematodes, annelids, mollusks, arthropods, echinoderms, and chordates
