Reviewing Main Ideas 1 What is an Animal? Animals are many-celled organisms that must find and digest their own food. Invertebrates are animals without backbones, and vertebrates have backbones. Symmetry is the way that animal body parts are arranged. The three types of symmetry are bilateral, radial, and asymmetrical.
60
Sponges, Cnidarians, Flatworms, and Roundworms
Reviewing Main Ideas 2 Sponges, Cnidarians, Flatworms, and Roundworms Sponges have no tissues. Adult sponges are sessile and obtain food and oxygen by filtering water. Cnidarians are radially symmetrical, and most have tentacles with stinging cells to get food. Flatworms and roundworms have bilateral symmetry. They have parasitic and free-living members.
61
Mollusks and Segmented Worms
Reviewing Main Ideas 3 Mollusks and Segmented Worms Mollusks are soft-bodied animals that usually have a shell and an open circulatory system. Gastropods, bivalves, and cephalopods are types of mollusks. Annelids have segmented bodies. A body cavity separates internal organs from the body wall.
62
Arthropods and Echinoderms
Reviewing Main Ideas 4 Arthropods and Echinoderms Arthropods have exoskeletons that cover, protect, and support their bodies. Arthropods develop either by complete metamorphosis or by incomplete metamorphosis. Echinoderms are spiny-skinned invertebrates and have a water-vascular system.
63
Chapter Review Question 1 According to this diagram, the animal kingdom is divided into _______. LE 1.1h
64
animals that eat plants and those that eat other animals
Chapter Review animals that eat plants and those that eat other animals B. animals with a backbone and those without a backbone LE 1.1h
65
C. animals with bilateral symmetry and those with radial symmetry
Chapter Review C. animals with bilateral symmetry and those with radial symmetry D. animals with cells and those without cells LE 1.1h
66
Chapter Review Answer The correct answer is B. This chart shows how animals can be divided into invertebrates, those without a backbone, and vertebrates, those with a backbone. About 97 percent of all animals are invertebrates.
67
Chapter Review Question 2 Describe the asexual stage in the life cycle of this cnidarian. LE 4.1b
68
Chapter Review Answer During the asexual stage the polyp, which developed from the larva, grows. The polyp then begins to form buds that become tiny medusae. After the medusae are released, they grow and begin the sexual cycle.
69
Question 3 Answer Why are sponges called filter feeders?
Chapter Review Question 3 Why are sponges called filter feeders? Answer Sponges filter food out of the water that flows through their bodies. Their specialized collar cells have flagella that keep water moving through the sponge. LE 5.1d
70
Question 4 Which is a characteristic of gastropods? A. secrete mucus
Chapter Review Question 4 Which is a characteristic of gastropods? A. secrete mucus B. sucking disk on two ends C. two shell halves D. well developed head LE 1.2g
71
Chapter Review Answer The correct answer is A. The mucus secreted by gastropods allows them to glide across objects on their large muscular foot.
72
Chapter Review Question 5 Sheree told a friend that she is not afraid of any arthropods but that she would rather pick up a millipede than a centipede. From what you know about these two arthropods, why do you think she may have said this? LE 5.1e
73
Chapter Review Answer Centipedes are predators that use venom to capture their prey while millipedes eat plants. Sheree probably did not want to risk getting a bite from a centipede.
74
Question 1 Which is a characteristic of all animals?
Standardized Test Practice Question 1 Which is a characteristic of all animals? A. bilateral symmetry B. digest their food C. have a backbone D. reproduce asexually LE 1.1h
75
Standardized Test Practice
Answer The correct answer is B. All animals use digestion to break large food particles down into smaller substances that their cells can use. The other characteristics listed describe only some animals.

Question 2 What does this diagram show about the life cycle of the tapeworm? LE 5.1
77
A. Humans become infected by eating tapeworm segments.
Standardized Test Practice A. Humans become infected by eating tapeworm segments. B. If humans eat infected meat, tapeworms can attach to their mouth. LE 5.1
78
C. Tapeworm larvae burrow into cow’s muscles. D. Tapeworms live
Standardized Test Practice C. Tapeworm larvae burrow into cow’s muscles. D. Tapeworms live in the grass where cows will eat them. LE 5.1
79
Standardized Test Practice
Answer The correct answer is C. If cows eat grass contaminated with fertilized tapeworm eggs, they become infected with tapeworms. After the eggs hatch, the larvae burrow into the cow’s muscle. Humans can get infected by eating improperly cooked meat.

Question 3 Which is a part of the digestive system where food and soil is ground? LE 1.2c
81
A. crop C. mouth B. gizzard D. waste removal tubes
Standardized Test Practice A. crop B. gizzard C. mouth D. waste removal tubes LE 1.2c
82
Standardized Test Practice
Answer The correct answer is B. After food and soil are ground in this muscular structure, it is passed to the intestine. Undigested soil and wastes leave the worm through the anus.
83
Standardized Test Practice
Question 4 Which is a characteristic of spiders that distinguishes them from other arthropods? A. They are predators. B. They have five pair of legs. C. They have spiny skin. D. They weave webs. LE 1.1h
84
Standardized Test Practice
Answer The correct answer is D. Some spiders weave webs to capture their prey. Spiders are members of the arachnids. Arthropods in this group have two body regions and have four pairs of legs.
85
Question 5 What would this sea star use its tube feet for?
Standardized Test Practice Question 5 What would this sea star use its tube feet for? LE 1.2g
86
A. absorb prey B. capture prey C. digest prey D. protection
Standardized Test Practice A. absorb prey B. capture prey C. digest prey D. protection LE 1.2g
87
Standardized Test Practice
Answer The correct answer is B. The tube feet are part of the water vascular system of the sea star and work like suction cups. They help the sea star move and capture prey.
