Invertebrates quiz
| Term | Definition |
|---|---|
| An animal is... | Multicellular Eukaryotic Heterotrophic |
| Sponges | No tissues or organs; no symmetry; hollow bag |
| larva | an immature form of an animal that looks very different from the adult |
| Cnidarians | have stinging cells and take food into a central body cavity; hollow, radial symmetry; 2 stage life cycle larvae and medusa or polyp |
| polyp | vase-shaped body plan for a cnidarian fe- jellyfish |
| medusa | bowl-shaped body plan; designed for swimming |
| colony | a group of many individual animals |
| coral reef | built by cnidarians |
| worms | bilateral symmetry, no legs, flatworms, round worms, segmented worms |
| parasite | an organism that lives inside or on another organism |
| host | the organism in or on which it lives |
| free-living organism | an organism that doesn't live in or on other organisms |
| scavengers | animals that feed on dead or decaying material |
| anus | where wastes exists; at the far end of the tube |
| closed circulatory system | what segmented worms have; blood moves only within a connected network of tubes called blood vessels |
| mollusks | soft, unsegmented bodies that are often protected by a hard outer shell; gills, mantle, foot, often radula, bilateral. symmetry, gastropods, bivalves, cephalopods |
| open circulatory system | the blood is not always inside blood vessels |
| gills | organs that remove oxygen from the water. |
| gastropods | largest group of mollusks. They include snails and slugs. have a single external shell or no shell at all |
| herbivores | animals that eat only plants |
| carnivores | animals that eat only other animals |
| radula | flexible ribbon of tiny teeth, to obtain food; organ |
| bivalves | mollusks that have two shells held together by hinges ang strong muscles. Includes oysters, clams, scallops and mussels |
| omnivores | animals that eat plants and animals |
| cephalopods | an ocean dwelling mollusk whose foot is adapted to form tentacles around its mouth. Only mollusks with a closed circulatory system fe octopus, squid |
| arthropods | divided into 4 major groups; crustaceans, arachnids, centipedes and millipedes, and insects. Invertebrates that have an external skeleton, a segmented body, and jointed attachments called appendages |
| exoskeleton | a waxy water-proof covering. Protects the animal and helps prevent evaporation of water |
| molting | shedding an outgrown exoskeleton |
| antenna | an appendage attached to the head that contains sense organs |
| crustaceans | an arthropod that has 2-3 body sections, 5 or more pairs of legs, and 2 pairs of antennae like shrimp lobster or crabs |
| metamorphosis | a process in which an animal's body undergoes dramatic changes in form during its life cycle |
| arachnids | arthropods with 2 body sections- cephalothorax and abdomen, four pairs of legs, and no antennae fe spiders-predators, ticks-parasites, mites-parasites, scorpions-predators |
| abdomen | the hind section. Contains the reproductive organs and part of the digestive system. |
| insects | arthropods with 3 body sections, 6 legs, 1 pair antennae, and usually 1-2 pairs wings like beesflies and moths. head: senses, compound eyes, antennae, many mouth part adaptations thorax: legs and wings attached, 3 pair legs abdomen:many internal organs |
| thorax | midsection, the section to which wings and legs are attached |
| complete metamorphosis | 4 diff. stages; egg, larva, pupa, and adult |
| pupa | stage after larvae when insect is enclosed in a protective covering |
| gradual metamorphosis | an egg hatches into a nymph that resembles an adult and which has no distinct larval stage stages are less distinct |
| bilateral symmetry | one line fe fish |
| radial symmetry | many lines fe seastar |
| centipedes | 1 pair of legs for each bodysegment carnivorous |
| millipedes | 2 pairs of legs for each body segment herbivores |
| echinoderms | endoskeleton, radial symmetry, bumpy or spiky surface, water vascular system that helps with transport of materials and with movement, tube feet. live in saltwater |
| nymph | a stage of gradual metamorphosis that usually resembles the adult insect |
| endoskeleton | an internal skeleton |
| water vascular system | the internal system of fluid filled tubes in echinoderms |
| tube feet | extensions of an echinoderms water vascular system that stick out from the body and function in movement and obtaining food |
