Lab final Flashcards
all animals…..
- eukaryotes
- multicellular
- heterotrophic
- require O2 for respiration
most animals
- reproduce sexually
- display radical or bilateral symmetry
- motile during some phases of their life cycle
- have tissues, organs, and organ systems
3 types of symmetry
- asymmetrical ( no symmetry)
- bilateral (two sides)
- radical (bicycle wheel)
Parazoa
- subtype in the animal kingdom
- sponges
- asymmetry
- no tissue or organs
three developing tissues layers of the eumetazoan
- ectoderm
- endoderm
- mesoderm
Porifera
- SpongeBob
spicules
tiny skeletal elements like rods that support the body of a sponge
spongin
the tough fibrous protein used for spicules
spongocoel
the inside chamber of a Spongebob
Ostria/Ostium
small pores in the sponge
osculum
a single large [exit for water] opening in the Spongebob
hermaphroditic
both male and female gonads
fragmentation
budding
cnidaria consists of…
Jellyfish, corals, and anemones
cnidocytes
stinging cells
class Hydrozoa
a polyp is the dominant body form; examples are hydra and obelia
class Scyphozoa
medusa is the dominant body form; an example is jellyfish
class Anthozoa
the polyp body form is dominant; examples are corals and anemones

echinoderms
seastars and sand dollars and stuff like that
foramen magnum
the skull opening where the spine enters
predator field of vision
- binocular
- depth of perception
prey field of vision
- peripheral vision
- wider ranger
spell and name the three types of animal diets
- herbivores
- carnivores
- omnivores
name all possible teeth
- incisors
- canines
- premolars
- molars
- carnassial teeth
sagittal crest
is the point of attachment for the muscle that runs from the top of the head to the jaw
turbinates
indicates the ability to smell
large eye sockets
usually nocturnal and has 10/10 vision
population
A group of individuals of the same species occupying the same geographical location at the same time. An example of a population is the humans on your college campus. You are all the same species, Homo sapiens, and you share the same habitat, the campus.
community
All the populations that occupy the same geographical location at the same time. To continue the example from above, the campus community consists of the human population plus all the other populations living on campus, such as birds, insects, plants, and bacteria.
ecosystem
The combination of a community with the non-living physical and chemical environment. The non-living aspects of the campus include such things as the climate, water, food, and shelter for all the organisms living in the community. On a college campus, this might include buildings, rocks, any standing water, weather, and all the organisms listed above.
primary producers
These are autotrophic (self- feeders) organisms that capture the sun’s energy through photosynthesis. Examples include plants, phytoplankton, and algae.
predation
It occurs when an organism from a higher trophic level, the predator, eats prey, an organism from a lower trophic level. . This type of interaction benefits the predator at the expense of the prey.
parasitism
is a type of interaction where the parasite is benefited and the host is harmed. Parasitism differs from predation in that the host is seldom killed by the parasite and the parasite is usually smaller than the host.
competition
occurs when organisms compete for the same resource.
intraspecific competition
It may be between members of the same species,
interspecific competition
or it may be between two different species
commensalism
in which one organism benefits without harming the other organism.
mutualism
in which both organisms derive positive benefits from the interaction.
lag phase
initial flat phase in which a population is adjusting to its habitat before it begins to grow rapidly.
log or exponential phase
period of the rapid increase in population number; indicates that there are sufficient resources present to support rapid growth.
equilibrium phase
population number stabilizes; indicates that the population has reached the size that the resources can support (carrying capacity), but that there are not enough resources to support additional growth.
type 1
low mortality rate in the young, most individuals die in old age; typically, type I organisms have a low birth rate and nurture and protect their young; example are humans and large mammals.
type 2
the mortality rate is relatively steady throughout the life span; examples are birds, small mammals, and reptiles.
type 3
the mortality rate for the young is very high, few individuals reach old age; typically, type III organisms have a very high birth rate and provide no protection to their young; example are frogs, sea urchins, and insects.
find the spicules, spongocoel, choanocytes, amoebocytes, and ostia
picture <3
find the digestive glands, ossicles, spines, gonad, cardiac stomach, pyloric stomach, madreporite, Ambulacral grove, Ampulla of tube feet of a sea star

picture <3
oviparous
means egg-laying, eggs are laid in an egg case
ovoviviparous
eggs are formed inside the mother, and then hatched the pups are born alive
viviparous
shark pups are born live after developing in the mother
Placoid scales Gills External Yolk sac Dogfish embryo or ‘pup’ Uterus Eyes (eye sockets) Pharynx Heart Heterocercal tail Caudal fin Pelvic fin Stomach Spongocoel Choanocytes SHARK
