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)

4. It is important that when scientists in Mongolia work on a species, a scientist in Brazil knows which one. Anemone http://www.sydneyaquarium.com.au/Dow nloads/INT/Wallpaper_1024x768_Warat ahAnemone.jpg http://www.nmessences.com/healing_ images/anemone_white_b1.jpg

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

8. 5.5.3 A closer look at Plants: There are 4 phyla: 1.Bryophyte – The mosses 2.Filicinophyte – The Ferns 3.Coniferophyte – The Conifers 4.Angiospermophyte – The flowers

9. Bryophytes – The mosses Simple non, vascular (no xylem and phloem.) no proper roots but have rhizoids, reproduce with spores. Male gamete swims to female! http://www.dcr.virginia.gov/natural_heritage/images/TIa_ph oto1_500.JPG http://www.anbg.gov.au/bryophyte/photos- 800/grrimmia-sp-exposed-rock-WA.jpg

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

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

13. 5.5.4 The Animal invertebrates in detail Invertebrates are animals without backbones there are 6 phyla: 1.Porifera – sponges. 2.Cnideria - corals. 3.Platyhelminthes – flat worms. 4.Annelida – segmented worms. 5.Mollusca – snails, octopi. 6.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_10 24x768_WaratahAnemone.jpg

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

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

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/shutte rstock_701650.jpg http://www.americanaquariumproducts.com/images/ graphics/octopus.jpg

19. Athropoda – insects, spiders, crustaceans Jointed legs. Hard chitin exoskeleton. Bilateral symmetry.
