Biology

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

Free-swimming, umbrella shaped form of coelenterate

cylindrical body type that is sessile and has mouth facing up

shipping center of cell

protein factories of the cell

store food and other materials for later

infects the lymphatic system and causes elephantiasis

parasites that mostly live in

free-living flatworms that live as scavengers

obtain oxygen through its skin

outside cell membrane that provides support and protection

fluid medium of cell

internal skeleton to maintain the cell shape

protein molecules

“power plants” of a cell

region within nucleus that makes ribosomes

cytoplasm separates to form 2 cells

squid, octopus, and nautilus

study of cells

large mouth like opening of a sponge

incurrent pores of sponge where water enters through

microtubule organizing center

named for rotating appearance of the cilia on their front ends

animals with no backbone

Marine slugs

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

hairlike projections

only cephalopod with external shell

separates nucleus from rest of cell

bristles that help earthworms move through soil

false feed of amoeba

A marine invertebrate of the phylum

holds the shells together

clams and scallops

snails, slugs, conchs, and nudibranchs

sessile invertebrates that lack a nervous system

phosphate molecule that serves as energy carrier of cell

torpedo shaped that moves by “jet propulsion”

all living things are composed of cells

largest class of segmented worms

beautiful “flowers” of the ocean with stinging tentacles

protozoan that uses pseudopods to move and engulf prey

barrel-shaped ciliate that feeds on paramecia

parasite known fort feeding on blood

protozoan that possesses a flagellum, chloroplasts, and an eyespot

trumpet shaped ciliate

cell engulfs solid food; “cell eating”

cell engulfs liquids; “cell drinking”

organelle that acts as a recycling center
