  1. 5.5 Classification “You failed your Latin exam?!! But Sweaty, all you friends names have Latin roots….” http://www.cartoonstock.com/newscartoons/cartoonists/cga/lowres/cgan893l.jpg

  2. 5.5.1 Why Classify? • The classification system we use was invented by Carolus Linneus (1707-1778) • It is called the Binomial system because all organisms are given 2 names – their Genus name and their species name. e.g Homo sapiens, (man), Mytilus edulis (common mussel)

  3. Mytilus edulis Homo sapiens? http://www.marlin.ac.uk/imgs/Species/Mollusca/o_Mytedu.jpg

  4. It is important that when scientists in Mongolia work on a species, a scientist in Brazil knows which one. Anemone Anemone http://www.sydneyaquarium.com.au/Downloads/INT/Wallpaper_1024x768_WaratahAnemone.jpg http://www.nmessences.com/healing_images/anemone_white_b1.jpg

  5. It allows us to group similar organisms http://www.tigertouch.org/images/cats/lion.jpg http://www.felinest.com/images/bengal-tiger.jpg http://www.no-pest.com/MountainLion6.jpg http://i1.treknature.com/photos/6688/imgp1500a1a-copy1.jpg http://media.photobucket.com/image/genus%20felidae/crowskyler/animania/clouded_leopard3.jpg

  6. 5.5.2 There are 7 levels of Classification: Kingdom Phylum Class Order Family Genus Species Make up a pneumonic to remember this list in order. King Philip Comes Over For Great Sausages. Homework: Classify Humans and one plant completely .

  7. The 5 Kingdoms No cell walls Cellulose cell walls Chitin cell walls Many types of cell wall NAG-NAMA cell walls Multi-cellular Multi-cellular Single cellular Single + Multi-cellular Single cellular Many feeding types Many feeding types Photo-autotroph Saprotroph Heterotroph

  8. 5.5.3 A closer look at Plants: There are 4 phyla: • Bryophyte – The mosses • Filicinophyte – The Ferns • Coniferophyte – The Conifers • Angiospermophyte – The flowers

  9. Bryophytes – The mosses • Simple non, vascular (no xylem and phloem.) no proper roots but have rhizoids, reproduce with spores.

  10. Filicinophytes – the ferns • Has stems roots and leaves. Reproduces by spores. Male gamete swims to female. http://www.centralfloridafarms.com/fern-vine/foxtail-ferndrm-web.jpg http://farm1.static.flickr.com/205/519433609_f1a29201d7.jpg

  11. Coniferophytes – The conifers • Truly vascular. Reproduce with pollen. Make cones with seeds in. • Leaves are needle shaped to conserve water. http://www.cambridge2000.com/gallery/images/P3075134.jpg http://www.denverevergreen.com/images/pine_cones-left.gif

  12. Angiospermophytes- Flowering plants • Have proper flowers. Truly vascular. http://www.umanitoba.ca/Biology/BIOL1030/Lab8/images/Helianthus_spp(Sunflower).jpg http://www.ipaw.org/invaders/reed_canary_grass/ReedCanaryGrassC_lg.jpg

  13. 5.5.4 The Animal invertebrates in detail Invertebrates are animals without backbones there are 6 phyla: • Porifera – sponges. • Cnideria - corals. • Platyhelminthes – flat worms. • Annelida – segmented worms. • Mollusca – snails, octopi. • Athropoda – insects, spiders, crustaceans

  14. Porifera – the sponges • No mouth or anus. No symetry. http://www.middleschoolscience.com/spong.jpg

  15. Cnideria – Corals, hydra, jellyfish • Have a mouth and anus. Have radial symmetry. http://www.sydneyaquarium.com.au/Downloads/INT/Wallpaper_1024x768_WaratahAnemone.jpg

  16. Platyhelminthes- flatworms • Have mouth and anus. Have Bilateral symmetry. Soft with no skeleton. http://rivers.snre.umich.edu/www311/OrganismPhotos/Platyhelminthes.GIF

  17. Annelida – segmented worms Hydrostatic skeleton Many segments Bilateral symmetry http://www.southtexascollege.edu/nilsson/4_GB_Lecture_figs_f/4_GB_23_AnimaliaInvert_Fig_f/Annelid.GIF

  18. Mollusca – snails, octopi Have a mouth and anus. Most have a calcium carbonate shell. Bilateral symmetry. Hard rasping ‘radula’ is used for feeding. http://z.about.com/d/animals/1/0/V/7/shutterstock_701650.jpg http://www.americanaquariumproducts.com/images/graphics/octopus.jpg

  19. Athropoda – insects, spiders, crustaceans • Jointed legs. Hard chitin exoskeleton. Bilateral symmetry. Segmented body http://img.quamut.com/chart/6861/01_atlantic_common_crab.jpg http://tintedglasses.files.wordpress.com/2007/06/cockroach-3.jpg http://www.hhcc.com/wp-content/uploads/2006/03/spider.jpg
