1. How can you tell that the flower you dissected yesterday was a monocot?___ _______________________________
2. __________________ are flowering plants.
3. __________________ reproduce with cones.
4. Organisms that are ____________have the ability to make their own food from sunlight (or other chemical pathways.)
 5. Organisms that are ___________ must eat other organisms

5. Kingdom Animalia

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

7. 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.

8. Body Plans: Symmetry
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. Which figure has bilateral symmetry? Which has radial symmetry?

10. ~ Protection and Support ~
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.

11. 95% of all animals are in this group
The Invertebrates
8 main phyla
No backbones
95% of all animals are in this group

12. Phylum Porifera: the Sponges
simplest form of animal life
live in water
Do not move around - sessile
no symmetry
Pores (holes) all over body

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

14. Phylum Porifera~
Examples: Tube Sponge, Glass Sponge, Sea Sponge

15. Phylum Cnidaria: jellyfish, hydra, sea anemones, and corals
2 different shapes
Medusa - like a jellyfish Polyp - like a hydra

16. Phylum Cnidaria~ Live in water Most have tentacles
catch food with stinging
cells
gut for digesting

17. Phylum Cnidaria~
Examples - Jellyfish, Hydra, sea anemones, and corals

18. Phylum Platyhelminthes: Flatworms - Planaria, Tapeworms
Flat, ribbon-like body
Live in water or are parasites
bilateral symmetry
Some parasites - tapeworm

19. Tapeworms are
Parasites that lives in intestines of host absorbing food

20. Phylum Platyhelminthes ~
Liver Fluke
parasite
lives inside
of host

21. Phylum Nematoda: roundworms – hookworms trichinella
Round, tubular body
small or microscopic
bilateral symmetry
have both a mouth and anus
Live in water or are parasites

22. Phylum Mollusca: Mollusks: snails, squid, clams
Soft bodies
Hard Shells
Live on land or in water
have a circulatory system and a complex nervous system.
Important food source for humans

23. Phylum Mollusca Class Gastropoda stomach-footed - moves on stomach
snails and slugs
may have 1 shell

24. Phylum Mollusca
Class Cephalopods “head foot”
squids and octopuses
internal mantel

26. Class Bivalves 2 shells hinged together clams, oysters,
scallops and mussels

27. Phylum Annelida – Segmented worms – Earthworms, Bristleworms, Leeches
Body divided into segments (sections)
Live in water or underground
have a nervous and circulatory system

29. ~
Class Earthworms eat soil and breakdown organic matter, wastes provide nutrients to soil
Class Bristleworms

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

31. Phylum Echinodermata "spiney skin"
Hard, spiney skin
Live in salt water
Radial symmetry
endoskeleton

32. Phylum Echinodermata ~
Sea stars, sea urchins, sand dollars & sea cucumbers

34. Phylum Arthropoda: most successful & largest group of organisms on earth
Body divided into sections/segments
Exoskeleton
Jointed legs
well developed nervous system

35. Phylum Arthropoda 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

36. Phylum Arthropoda: Subphylum Chilicerata
Class Arachnida:
spiders, scorpions, mites & ticks
no antennae
4 pairs of legs
2 body regions - cephalothorax & abdomen

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

38. Phylum Arthropoda - Subphylum Chilicerata
Class Pycnogonida: Sea spider

39. Phylum Arthropoda Subphylum - Crustacea
Aquatic ones have gills
2 antennae
2 body regions or segmented
Shrimp, lobsters, crabs, barnacles, isopods (rolly polly’s)

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

42. Phylum Arthropoda: Subphylum Uniramia
Class Insecta: grasshoppers, ants, butterflies, bees
paired antennae
3 pairs of legs
2 body regions - head, thorax & abdomen

44. Phylum Arthropoda Subphylum Uniramia
Class Diplopoda

Have 2 pairs of legs per segment
Primarily herbivores & decomposers

45. Phylum Arthropoda Subphylum Uniramia
Class Chiopoda: Centipedes

5 classes
Fish
Mammals
Reptiles
Amphibians
