What is the difference between vertebrates and invertebrates? A vertebrate has a backbone, the invertebrates do not have a backbone. 12.What are sponges? Simple animals with pores and canals. 13. What do sponges look like? Look like underwater plants of various shape and color. 14. Draw two examples of sponges: 1 2 15. Explain how the sponges use a network of pores and canals: Water enters the sponge through the pores, flows through the canals into the center of sponge then out the top. 16. Where in the ocean do sponges spend their entire adult life? Attached to something on the bottom of the ocean. 17. Describe the function of the three types of cells found in sponges: a)Cells to grab incoming food b)Cells to make sperm and egg c)Cells to make the exoskeleton 18. Explain how the sponge uses filtration: Water, oxygen, food, and sperm are filtered out of the water as it moves down the canals. 19. Describe the sexual and asexual ways that sponges reproduce: Sexual By fertilizing an egg with sperm that it filtered out of the water Asexual By budding! A new sponge grows off of the side of the adult, breaks off and becomes a separate sponge. 20. List a practical way tht we use sponges. What part of the sponges are we actually using: We use the skeleton of the sponge for cleaning. 21. Draw the following 5 examples of animals found in the phylum coelenterata: HYDRA Sea Anemone Brain coral 22. Why are coelenterates called the stinging celled animals? They have special cells that fires poison darts at their prey when they are touched. 23.What are tentacles? Arm like parts that surround the mouth. 24. Where are the stinging cells located on the coelenterates? ON THE TENTACLES! 25. What is the job of the tentacle? Presents the stinging cells for use. Grabs food and puts it in the mouth. 26. Explain how and why the stinging cells are fired by the coelenterate: Automatically fires just as soon as a prey touches a tentacle. 27. Explain how the stinging cells and the tentacles work together to get food: Stinging cells paralize prey, tentacles put it in the mouth. 28. What is a colony creature? Groups of animals that function as one animal. 29. Give two examples of colony creatures; CORAL REEF PORTUGESE MAN OF WAR 30. Why can you always see the tentacles of some coelenterates and you can’t always see the tentacles of others?? Different fishing styles! Jellyfish, sea anemome dangle their tentacles out all the time. Coral only stick out their tentacles at night. 31. Describe the cell layers of the coelenterates: Endoderm = inner layer Jelly layer = middle layer Ectoderm = outer layer 32.

Immature proglottids are new tapeworm segments. Mature proglottids have developed sex organs Gravid proglottids are full of eggs. 37. Sketch the tapeworm and label the three types of proglottids. Scolex Mature proglottids Immature proglottids Gravid proglottids 38. Describe the tapeworm life cycle: 1.Eggs are swallowed 2.Eggs hatch in stomach 3.Worm swims to the small intestine. 4.Bites into the wall of the small intestine and waits for your food. 39. Describe the two ways that people can get tapeworms into their body: Method # 1: Eat raw pork containing the tapeworm. Method # 2: Swallow eggs off of our hands that we picked up throughout the day. Which method do you think happens most often? We swallow eggs off of our hands. 40.What is the Trichina? Tapeworm that gets into pork. 41. Describe two ways that tapeworm infection can be controlled: Cook pork well done And Wash your hands good after using the bathroom. 42. Why is the planarian considered a free living organism? It is a consumer, but it is not a parasite. 43. What does the planarian eat? Where is it found? Eats = Night feeder. Eats dead things in the water Found = Ponds and streams all over the world. 42. Draw and label a planarian: Eye spots chemoreceptors mouth What are: Eye spots? Photoreceptors that allow the worm to measure light and dark. No image! Chemoreceptors Organs used by the worm to follow the chemical trail of some dead decaying thing. Funky digestive system? Incomplete digestive system. Food and body waste use the same hole. How can a planarian eat objects bigger than it is? Planarian follows the chemical trail until it finds the dead fish. Pukes up its stomach, and lays it on the fish. Eats, then pulls it in. 43. What is an incomplete digestive system? A system where there is only one opening into it. Mouth only,no anus. 44. Draw and explain how the planarian can use REGENERATION as a way to reproduce and a way to heal itself: Pulls itself into,then grows back missing parts. 1 becomes 2. If a piece of the worm is eaten, it can grow missing body parts. 45.What is a HERMAPHRODITE? A creature that contains male and female sex organs. Why is it useful? It can breed with any other planarian that it meets. 46.Which phylum first developed separate sexes? NEMATODA (round worms) 47. What do the worms look like that belong to the phylum Nematoda? Drawing of the Nematode Description 1)Microscopic 2)Round like a pen with pointed ends. 3)Female much bigger than the male. 48. What phylum do HOOKWORMS belong to? NEMATODA 49 a) Where do hookworms live in the human body? In the small intestine b) How do they attach themselves to the human body?

The females crawl in and out of the anus to lay her eggs. It makes the anus ITCH. D) Why do they reproduce this way? To get you to scratch and spread her eggs. 52.Why do most restaurants INSIST that all employees wash their hands after they use the restroom? To Wash away worm eggs before they return to work. 53.

Draw and explain how the bivalve buries itself in the sand and uses its inlet and outlet siphons: Pix of buried bivalve What is the purpose of the siphons? To let water in and out of the bivalve. Why did the bivalve bury itself? To hide from sea stars. 67.What is the mantle? A thin layer of skin inside the shell that completely covers the animal. 68. What is the function of the bivalve shell? PROTECTION and MOVEMENT 69.Explain how a pearl is produced: a)A piece of sand gets inside the oyster shell. b)Hurts the oyster c)The oyster wraps the sand particle up in mucus. d)When the mucus hardens, we call it a pearl. 70.What is a Gastropod?
