Science Chapter 10

What are the characteristics of mollusks? soft body covered by shell, mantle, foot, bilateral, open circulatory system, gills with cilia, invertebrates, two-way digetive system
What are the characteristics of bivalves? 2 shells, omnivore, slow, watery environments
What are the characteristics of cephalopods? no shell, closed circulatory system, carnivore, large eyes to see, large brains- they remember things and are smart, jet propulsion
What are the characteristics of gastropods? stomach-footed, herbivores, carnivores, radula
What are the characteristics of arthropods? jointed legs, invertebrates, external skeleton, segmented body, appendages, major groups: crustaceans, arachnids, centipedes/millipedes, insects
What are the characteristics of millipedes? more than 80 segments, 2 pair of legs on each segment, scavengers
What are the characteristics of centipedes more than 100 segments, 1 pair of legs on each segment
What are the characteristics of insects? 3 body sections, 6 legs, 1 pair of antennae, 1 or 2 pairs of wings
What are the benefits of mimicry or camouflage (ex: walking stick)? if it is prey, predators will ignore or not notice it
What are the different types of metamorphosis? complete, gradual/incomplete
What are the stages in complete metamorphosis? egg, larva, pupa, adult (ex: beetles, butterflies, flies, ants)
What are the stages in gradual metamorphosis? egg, nymph, adult (ex: grasshoppers, termites, cockroaches, dragon flies)
What is a radula? a flexible ribbon of tiny teeth to obtain food found in gastropods (snails/slugs)
What is a larva? the immature form of an animal that looks very different from an adult (used in complete metamorphosis)
What is a pupa? the third stage of complete metamorphosis in which an insect changes from a larva to an adult
What is an echinoderm? invertebrates with an internal skeleton and a system of fluid-filled tubes called a water vascular system that live in salt water
How does a grasshopper get oxygen?
What are the insect mouthparts? lapping mouthparts (fly), sucking mouthparts (butterfly), chewing mouthparts (ant)
How can each mouthpart be used? lapping- lap up decaying flesh sucking- coiled tube, used as a straw chewing- sharp edge cuts through food
What are the differences between an insect and an arachnid? insect- three body sections, wings, antennae, six legs arachnid- two body sections, eight legs, no antennae, no wings
What are the kinds of symmetry? (study notes) bilateral, radial
