Echinoderm Review For Quiz & Dissection

Questions #1 What kingdom are starfish in?

Question #2 What phylum are starfish in?

Question #3 What systems are present in starfish?

Question #4 What symmetry do starfish have?

Question #5 What are the two ways in which starfish reproduce?

Question #6 What do starfish eat?

Question #7 Name two other animals in this phylum besides starfish.

Question #8 Compare and contrast the water vascular system to our circulatory system.

Question #9 Explain the difference between an exoskeleton and an endoskeleton.

Question #10 This disk shaped structure is the opening for water to come into the starfish. a.Tube feet b.Mouth c.Ampullae d.Madreporite

Question #11 This structure is used for gas exchange and excretion as well as for movement. a.Ampullae b.Tube feet c.Mouth d.Stomach

Question #12 This structure produces sperm and eggs. a. Ray b. Digestive gland c. Reproductive organ d. Eyespots

Question #13 This structure produces digestive enzymes that break down food. a.Digestive gland b.Radial canal c.Mouth d.Ampullae

Question #14 This structure allows water to move around the center of the body before it goes to the rays (arms). a.Radial canal b.Ampullae c.Tube feet d.Ring canal

Question #15 This structure makes the tube feet open and close. a.Ampullae b.Mouth c.Pedicellariae d.Stomach

Question #16 This structure is sometimes pushed out of the body to break down food. a.Stomach b.Anus c.Mouth d.Digestive glands

Question #17 This structure runs down each ray (arm) to move water. a.Ring canal b.Radial canal c.Ampullae d.Tube feet

Question #18 This structure determines light form dark. a. Mouth b. Anus c. Pedicellariae d. Eyespots

Question #19 This structure looks like pinchers and aids in cleaning the surface of the body. a.Ring canal b.Radial canal c.Ampullae d.Pedicellariae

Question #20 How could you double the population of a starfish colony?

Question #21 A C B

Question #22 D E

Question #23 F G H

Question #24 I

Question #25 J

Answers 1.Animalia 2.Echinoderm 3.Digestive, Reproductive, Nervous, Excretory 4.Radial 5.Sexual and regeneration 6.Worms or clams 7.Brittle star, sea urchin, sand dollar, sea cucumber, sea lilies, feather star

8.Compare: The water vascular system transports food and waste around to the cells in the body just like our blood does. Contrast: The water vascular system uses water to move materials around the body and humans use blood. 9.Exoskeleton is a hard structured used for support found on the outside of the body (like lobsters). An endoskeleton is a hard structure used for support on the inside of an animal.

10.D 11.B 12.C 13.A 14.D 15.A 16.A 17.B 18.D 19.D 20.Cut the starfish in half and put them in the water to regenerate.

21. A. Arms / Rays B. Eyespots C. Madreporite 22. D. Tube Feet E. Mouth 23. F. Ring Canal G. Radial Canal H. Ampullae 24. I. Digestive Gland 25. J. Reproductive Organ (Gonad)
