Test 11 Review Flashcards
invertebrates that are aquatic that have two body forms, consist of gastrovascular cavity
coelenterates
invertebrates that have many pore and no nervous system
sponges
roundworms are also known as
nematodes
microscopic with spinning rings of cilia, 500-1000 cells
rotifers
have a muscular foot and a visceral hump
mollusk
marine invertebrates with spiny skin; star fish, sand dollar
echinoderms
animal-like, single-celled organisms
protozoa
main characteristics of mollusks
muscular foot
three groups of mollusks
bivalve, univalve, cephalopod
octopus, squid, nautilus
cephalopods
clam, oyster, scallop
bivalve
examples of univalves
slug, nail, nudibranch, conch
if bivalve get irritant in between mantle and shell, make pearl made of
nacre
gastropods file-like tongue
radula
only cephalopod with external shell
nautilus
examples of echinoderms
starfish, sand dollar, sea urchin, sea cucumber
kind of symmetry of adult echinoderms
radial
echinoderms have special body system called
water-vascular system
why rotifers not classified as protozoa
more than one cell
invertebrate animals with hollow bag and tentacles
coelenterates
two body forms of coelenterates
polyps, medusa
examples of coelenterates
jellyfish, sea anemone, coral, hydra
jellyfish body style
medusa
stinging cells on tentacles
cnidocytes
motile coelenterate body style
medusa
coelenterates that are tiny and form limestone cups
coral
animal that means pore-bearer
sponges
sponges mouth (osculum) that function as
excurrent pore
bristles on earthworm
setae
earthworms use for kidneys and filtering
nephridia
annelids that are parasites
leeches
Platyhelminths are
flatworms
flatworms that are free-living
planarian
platyhelminths that get into human liver, lungs, and blood
flukes
parasitic platyhelminths that eat digestive food
tapeworm
tapeworm’s head
scolex
roundworm that blocks lymphatic
filaria worm
roundworm that gets into intestines that drinks blood
hookworm
how control the spread of hookworm
don’t walk barefoot; good sanitation, disposal of wastes
roundworm from poorly cooked meat the bores into the muscle
trichina worm
disease from trichina worm
trichiosis
how to prevent the spread of ascaris
properly dispose of wastes; good sanitation
organisms that have single cell and classified by how move
protozoa
move with whip-like structures
flagellates
common flagellates that move like animal and make food like plant
euglena
euglena reproduction by splitting
binary fission
cell division of euglena binary fission is an example of
mitosis
disease caused by parasitic flagellate
African sleeping sickness
flagellate that spreads African sleeping sickness
trypanosome
disease caused by sarcodine
amoebic dysentery
most common sarcodine
amoeba
pseudopods purpose
move
ingest particles of food
causes malaria
plasmodium
main characteristic of sporozoans
sessile
says that all living things made of cells, come from preexisting cells
cell theory
four elements of cells
carbon, oxygen, nitrogen, hydrogen
most common chemical compounds found in living cells
proteins, lipids, carbohydrates, nucleic acids
