1. Chapter #7 Simple Animals

2. Chapter 7.1 Notes Traits of Animals 1.Animals can not make food 2.Most animals can move from place to place. 3.Animals have many cells. The cells make up tissues and organs that form systems. 4.Most animals have symmetry.

3. Symmetry 1.Radial- around a circle 2.Bilateral- cut into two halves. Radial Symmetry Bilateral Symmetry

4. Vertebrates- animals with a backbone. Invertebrates- animals without a backbone.

5. Animal Phyla (Phylums) 1.Stinging-cell 2.Soft-bodies 3.Spiny-skin 4.Chordates- the most complex 5.Jointed-leg 6.Sponges 7.Worms

6. Chapter 7.2 Notes Sponges-simple invertebrates that have pores. 1.Do NOT move about freely. 2.Live attached to rocks 3.Water enters through pores and leaves through an opening 4.Filter Feeders 5.2 cell layers thick. No tissue or organs. 6.Have 3 cell types a)Trap food b)Cover and protect c)Make skeleton 7.Reproduce sexually and asexually.

7. Stinging-cell animals- have hollow saclike bodies that lack organs. 1.Nematocysts- stinging cells 2.Tentacles- arm like parts 3.Radial symmetry 4.2 cell layers 5.One opening called a mouth 6.Disc- structure they fasten to the bottom of ocean or rocks. 7.Have muscle and nerve cells 8.Most reproduce sexually

9. Chapter 7.3 Notes 3 phyla of worms 1.Flatworms- the simplest worms. Examples: Tapeworm (parasite) and planarian (Free-living). 2.Roundworms- example: hookworms (parasite). 3.Segmented worms- most complex worms. Examples: earthworm (Free- living) and leeches (parasite).

10. Life Cycle of a Tapeworm 1.Pig or cows eat tapeworm eggs 2.Eggs hatch in pigs/cows intestine 3.Tapeworm enter blood stream 4.Form cysts 5.People eat undercooked meat 6.Tapeworms get in their intestine and grow 7.Body sections break off and leave the hosts body in solid waste.

13. Chapter 7.4 Notes Soft-bodied animals (Mollusc)- are animals with a soft body that usually have a shell inside or outside. Are invertebrates (no backbone). The body is covered by a thin, fleshy tissue called a mantle. Soft-bodied animals have a muscular foot for moving from place to place.

14. 3 classes of soft-bodied animals (Mollusc) 1.Gastropods- snails and slugs. Have wide muscular foot. Have single shell or no shell. 2.Bivalves- clams, oysters, and scallops. Have 2 shells. 3.Cephalopods-octopus, squid, and cuttlefish. Squids and cuttlefish ave shells inside their bodies, octopus no shell.

15. Snail Octopus SLUG

16. Drawing Rules 1.Use white paper…no lines. 2.Do NOT fold paper 3.Put a title on your paper (Earthworm) 4.Name, date, hour 5.Label all parts 6.Straight lines when labeling parts. 7.Color 8.Use a full sheet…draw big
