Biology

Hydra: round base body, a cylindrical stalk, and a mouth surrounded by tentacles

Medusa: Free-swimming, umbrella shaped form of coelenterate

Polyp: cylindrical body type that is sessile and has mouth facing up

Golgi apparatus: shipping center of cell

Ribosome: protein factories of the cell

Vacuole: store food and other materials for later

Filarial worm: infects the lymphatic system and causes elephantiasis

Flukes: parasites that mostly live in

Planarians: free-living flatworms that live as scavengers

Earthworm: obtain oxygen through its skin

Cell wall: outside cell membrane that provides support and protection

Cytoplasm: fluid medium of cell

Cytoskeleton: internal skeleton to maintain the cell shape

Enzymes: protein molecules

Mitochondria: “power plants” of a cell

Nucleolus: region within nucleus that makes ribosomes

Cytokinesis: cytoplasm separates to form 2 cells

Cephalopods: squid, octopus, and nautilus

Cytology: study of cells

Osculum: large mouth like opening of a sponge

Ostia: incurrent pores of sponge where water enters through

Centrosome: microtubule organizing center

Rotifers: named for rotating appearance of the cilia on their front ends

Invertebrates: animals with no backbone

Nudibranchs: Marine slugs

Conch: A tropical marine mollusk with a spiral shell that may bear lung projections and have a fluted lip

Cilia: hairlike projections

Nautilus: only cephalopod with external shell

Nuclear envelope: separates nucleus from rest of cell

Setae: bristles that help earthworms move through soil

Pseudopods: false feed of amoeba

Echinoderms: A marine invertebrate of the phylum

Adductor muscles: holds the shells together

Bivalves: clams and scallops

Gastropoda: snails, slugs, conchs, and nudibranchs

Sponges: sessile invertebrates that lack a nervous system

ATP: phosphate molecule that serves as energy carrier of cell

Squid: torpedo shaped that moves by “jet propulsion”

Cell theory: all living things are composed of cells

Sea Worms: largest class of segmented worms

Sea anemones: beautiful “flowers” of the ocean with stinging tentacles

Amoeba: protozoan that uses pseudopods to move and engulf prey

Didinium: barrel-shaped ciliate that feeds on paramecia

Leeches: parasite known fort feeding on blood

Euglena: protozoan that possesses a flagellum, chloroplasts, and an eyespot

Paramecium: Ciliated protozoan that appears slipper-shaped under microscope

Stentor: trumpet shaped ciliate

Phagocytosis: cell engulfs solid food; “cell eating”

Pinocytosis: cell engulfs liquids; “cell drinking”

Lysosome: organelle that acts as a recycling center

Trypanosome: parasitic flagellate that is transmitted by a tsetse fly bite; causes African sleeping sickness

Vorticella: body shape of upside down bell

Segmented worms: earthworms, sea worms, and leeches

Rays: arms of starfish

Robert Hooke: first scientist to observe cells through a microscope

Scolex: tapeworms head

Mantle: skinlike organ of mollusk that covers the internal organs and produces the cell
