1. 1. How can you tell that the flower you dissected last week was a dicot?____________________ _____________________________ 1. __________________ are flowering plants 2. __________________ reproduce with cones

2. 1. Organisms that are _________________have the ability to make their own food from sunlight or other chemical pathways. 2. Organisms that are ____________________ must eat other organisms Autotroph Heterotroph

5. Domain Eukarya Kingdom Animalia Multicellular Heterotrophs (consumers –eaters ) Lack cell walls Characteristics of Animals

6. Have nervous systems - respond to environment - homeostasis Locomotion = ability to obtain food Most develop from a zygote Single layer of cells surround fluid-filled space forming a hollow ball of cells called a gastrula. http://www.youtube.com/watch?v=lXN_sDnd1ng&feature=related

7. Animals that are irregular in shape are asymmetrical. Animals that are regular in shape are symmetrical. Animal has radial symmetry if it can be divided along any plane, through a central axis, into equal halves. Animal has bilateral symmetry if it can be divided down its length into similar right and left halves forming mirror images of each other.

9. Not all animals have a skeleton but some have  Exoskeletons: hard, waxy coating on the outside of body protecting internal organs, providing framework for support, and places for muscle attachment. Endoskeletons: support framework within body protecting some organs and a bracing for muscles to pull against.

10. 8 main phyla No backbones 95% of all animals are in this group

11. simplest form of animal life live in water Do not move around - sessile no symmetry Pores (holes) all over body

12. Filter Feeders: filtering particles of food from water using collar cells and then pumps the water out the osculum.

13. Examples: Tube Sponge, Glass Sponge, Sea Sponge

14. 2 different shapes  Medusa - like a jellyfish Polyp - like a hydra

15. Live in water Most have tentacles catch food with stinging cells gut for digesting

16. Examples - Jellyfish, Hydra, sea anemones, and corals

17. Flat, ribbon-like body Live in water or are parasites bilateral symmetry Some parasites - tapeworm

18. Parasites that lives in intestines of host absorbing food

19.  Liver Fluke  parasite  lives inside of host

20. Round, tubular body small or microscopic bilateral symmetry have both a mouth and anus Live in water or are parasites

21. Soft bodies Hard Shells Live on land or in water have a circulatory system and a complex nervous system. Important food source for humans

22. Class Gastropoda stomach-footed - moves on stomach snails and slugs may have 1 shell

23. Class Cephalopods “head foot” squids and octopuses internal mantel

25. 2 shells hinged together clams, oysters, scallops and mussels

26. Body divided into segments (sections) Live in water or underground have a nervous and circulatory system

28. Class Earthworms eat soil and breakdown organic matter, wastes provide nutrients to soil Class Bristleworms

29. Class leeches parasites that feed on blood of other animals Used in medicine too…

30. Hard, spiney skin Live in salt water Radial symmetry endoskeleton

31. Sea stars, sea urchins, sand dollars & sea cucumbers

33. Body divided into sections/segments Exoskeleton Jointed legs well developed nervous system

34. 3 subphylums: Classified into classes according to the number of legs, eyes and antennae they have. Subphylum Chilicerata is divided into 3 classes Arachnida, Merostomata, Pycnogonida

35. Class Arachnida: spiders, scorpions, mites & ticks no antennae 4 pairs of legs 2 body regions - cephalothorax & abdomen

36. Class Merostomata: Horseshoe crabs Ancient group of species Changed little over 350 million years Aquatic, mostly found on Atlantic & gulf coasts of United States.

37. Class Pycnogonida: Sea spider

38. Aquatic ones have gills 2 antennae 2 body regions or segmented Shrimp, lobsters, crabs, barnacles, isopods (rolly polly’s)

40. Subphylum Uniramia: 3 classes Insecta, Chilopoda, Diplopoda

41. Class Insecta: grasshoppers, ants, butterflies, bees paired antennae 3 pairs of legs 2 body regions - head, thorax & abdomen

43. Class Diplopoda Millipedes segmented animals Have 2 pairs of legs per segment Primarily herbivores & decomposers

44. Class Chiopoda: Centipedes Usually terrestrial carnivores Have 1 pair of antennae Are often poisonous, using modified front claws to immobilize prey

46. Anatomy of an Ant

47. 5 classes Fish Mammals Reptiles Amphibians Birds
