1. INVERTEBRATES Nematodes, Platyhelminthes, Annelids

2. GENERAL INFORMATION Invertebrates- organisms that lack a back bone Invertebrates are ecotherms (cold-blooded) Represents 95%-99% of the animal kingdom Multicellular No cell walls

4. VOCABULARY Parasite- an organism that lives inside of another organism and deprives the host of nutrients Osmosis- the diffusion of fluids through membranes or porous partitions Flame Cells- specialized excretory cell Hermaphrodite- an organism in which reproductive organs of both sexes are present Cephalization- development of a head by the concentration of feeding and sensory organs and nervous tissue at the anterior end Clitellum- a ring or saddle-shaped region of glandular tissue in the body wall of certain annelids that produces a mucus to coat and protect eggs

5. VOCABULARY Spicules- Provide support in sponges Polyp- Sessile; attached to one spot Medusa- Free swimming Osculum- Pores on sponges that release waste CO2 Filter feed- feed by straining suspended matter and food particles from water One way digestive system- Mouth that takes in the food and anus is where the food is disposed Two way digestive system- Only have one opening that takes in the food and dispossess it

6. VOCABULARY Diffusion- Movement of molecules form high to low concentration Osmosis- Movement of water molecules from high to low concentration Endoskeleton- Internal skeleton like bony or cartilaginous skeleton Exoskeleton- Hard outer layer that covers and protects the body Cephalization- Having a head or not having a head (doesn’t matter) Asexual-

7. VOCABULARY Sessile- Permanently attached not able to move Asymmetrical- Has a definite shape Symmetrical- Arrangement of body parts around a center point Bilateral- Can be divided into two similar halves when a line is drawn through a specific point Radial- Can be divided into similar pieces by passing through many points Clitellum- Forms mucus around the eggs Nephridia- Excretory system gets rid of nitrogenous

8. NEMATODA Symmetry: Bilateral Movement: Back and fourth thrashing

9. NEMATODA Nervous System: Present Digestive System: One-Way Excretory System: Present Circulatory System: Osmosis

10. NEMATODE Move by thrashing back and fourth Rings around nervous system Lives in soil and water Parasites Bilateral symmetry Lives off plant, insects, animals or humans to survive and reproduce Grow up to Eight meters

11. NEMATODA Respiratory System: Osmosis Skeletal or support system: No skeletal system, support through water Reproductive System: Sexual

12. ANNELIDS Symmetry: Bilateral Movement: Segmented body with 2 sets of muscles

13. ANNELIDS Nervous System: Present (Sense organs and primitive brain) Digestive System: One-way Excretory System: Present Circulatory System: Diffusion

14. ANNELID Respiratory System: Diffusion Support System: Absent Reproductive System: Sexual

15. ANNELIDS Segmented body Primitive brain Sense of organs Live in marine, freshwater and land Have male and female organs Have clitellum that forms mucus around eggs Ring of nerves

16. EARTH WORM

17. ROUNDWORMS

18. Flatworm Diagram

19. PLATYHELMINTHES Symmetry: Bilateral Movement: Controlled by a longitudinal circular layers of muscles Nervous System: Absent Digestive System: Two way

20. PLATYHELMINTHES Excretory System: Present Circulatory System: Osmosis/ Diffusion Respiratory System: Osmosis/ Diffusion Support or skeleton system: Absent Reproductive System: Both asexual and sexual

21. PLATYHELMINTHES Platyhelminthes means “Flatworm” Parasitic worms Live inn any moist areas Nerve cords go across the body Five groups of Platyhelminthes 3mm in length

22. TURBELLARIA Flat worm tropical environment

23. TREMATODA (Fluke) lives in intense conditions

24. CESTODA Parasitic flat worm

25. EXAMPLES OF PLATYHELMINTHES Tapeworm Fluke
