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)

• It is important that when scientists in Mongolia work on a species, a scientist in Brazil knows which one.

•It allows us to group similar organisms

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
Bryophytes – The mosses• Simple non, vascular (no xylem and phloem.)
no proper roots but have rhizoids, reproduce with spores. Male gamete swims to female!

Filicinophytes – the ferns• Has stems roots and leaves. Reproduces by
spores. Male gamete swims to female.

Coniferophytes – The conifers• Truly vascular. Reproduce
with pollen. Make cones with seeds in.
• Leaves are needle shaped to conserve water.

5.5.4 The Animal invertebrates in detailInvertebrates 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
Porifera – the sponges
• No mouth or anus. No symetry.

Cnideria – Corals, hydra, jellyfish• Have a mouth and anus. Have radial
symmetry.

Platyhelminthes- flatworms• Have mouth and anus.
Have Bilateral symmetry. Soft with no skeleton.

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
Mollusca – snails, octopiHave a mouth and anus. Most have a calcium carbonate shell.
Bilateral symmetry. Hard rasping ‘radula’ is used for feeding.

Athropoda – insects, spiders, crustaceans
• Jointed legs. Hard chitin exoskeleton. Bilateral symmetry. Segmented body
