some living descriptions

Protista-
  • unicellular eukaryotes, some multicelled forms
  • cell sturcture simple to very complex
  • some heterotrophs- protozoans
  • some autotrophs- algae
  • asexual repro, some both sexual, asexual
  • motile, non-motile, sizes- most microscopic but some may be 100m in length
  • cell walls
  • ex. paramecium, amoeba, euglena, diatoms, volvox, dinoflagellates, plasmodium, trypanosomes.
Fungi-
  • multicellular Eukaryotic
  • chitin cell walls, hyphae for cell forms, Yeasts are ovoid cells
  • heterotrophs (saphrophytes, parasites, mutualistic)
  • many species show both sexual and asexual
  • organisms range from microscopic to many meters in length
  • Ex. morels, corn smut, yeasts, bread mold, mildews
  • Plantae-multicellular Eukaryotes
  • cellulose cell walls
  • photosynthetic autotrophs
  • sexual repro
  • alternation of generations
  • sporophyte
  • gamophyte
  • can be marine, freshwater, terrestrial etc
  • starch as stored glucose
  • chloroplasts
  • vascular have xylem and phloem
  • avascular ex: mosses liver worts
  • Chlorophyll A.
Animalia-
  • Multicellular Eukaryotes
  • no cell wall
  • heterotrophs
  • typically motile
  • zygotes formed
  • glycogen
  • invertebrates/vertebrates
