Animal tissue consisting of one or more layers of cells, which have only one free surface because the other surface adheres to a membrane or another substance.
Epithelium
Mantle
Nematocysts
Epidermis
A sheath of tissue that encloses the vital organs of a mollusk, makes the mollusk's shell, and performs respiration.
Mantle

Explain the differences between invertebrates and vertebrates.
Vertebrates have backbones
Invertebrates have no backbones
Vertebrates have a brain
Invertebrates have an exoskeleton
Explain the difference between spherical and bilateral symmetry.
a. Bilateral - only 1 bilateral cut down the middle makes two mirror imaged halves
b. Spherial - any cut down the middle creates two mirror-imaged halves
c. Bilateral - any cut down the middle makes two mirror-imaged halves

Ventral
Dorsal
Posterior
Anterior
Which area of a bilaterally symmetric organism would contain the 'belly'?
Posterior
Anterior
Ventral
Dorsal
Which area of bilaterally symmetric organism would contain the head?
Ventral
Posterior
Anterior
Dorsal
What is another name for a system of sensitive cells that respond to stimuli such as sound, touch, and taste?
Nervous system
Brain
Ganglia
What is a system called that is designed to transport food and other necessary substances throughout a creature's body?
Nervous
Circulatory
Excretory
Respiratory
Explain the differences between the polyp and medusa forms.
Polyp is tubular-shaped and is mostly sessile (sticks to the sea-floor)
Medusa is the only one with stinging tentacles
Medusa is free-swimming
Medusa is bell-shaped
Polyp is the only one with stinging tentacles
Another name for a large coral colony is what?

Amebocytes
Coral reef
Herd
A shell is a tough, multilayered structure secreted by what part of the mollusk?
Visceral hump
Mantle
Epidermis
Explain the differences between univalve and bivalve shells.
Univalves have one shell and bivalves have two
Univalve has one foot while bivalves have two
Identify the symmetry possessed by organisms in the phylum Cnidaria.
Radially symmetric
Spherically symmetric
Bilaterally symmetric
No symmetry
An organism possesses what type of symmetry if it can be separated into two identical halves by any longitudinal cut through its center?
a. Spherical
b. Bilateral
c. Radial
Explain the differences between the anterior and posterior ends. Select all that apply.
a. Posterior is the back of the organism - where the top fin is
b. Posterior is the end with the head
c. Anterior is the end with the head
d. Posterior is the end with the tail
One biology book calls sponges "tireless, natural pumps". Why is this a good description of sponges?
Gemmule cells continually bring water into the sponge
Mesoglea is continually being pumped through the structure of the sponge by collar cells
Collar cells continually bring water into the sponge
What role(s) do amebocytes play in the anatomy of a sponge?
Select all that apply.
Transport
Digestion
Reproduction
When does a sponge produce gemmules?
When there is an irritant or clog in a spicule tunnel
When it wants to attract a mate
In inclement weather conditions this reproduction method is used
How do sponges get their prey?
The bait the fish to come close and then grab them
They use collar cells to bring prey in with water
The have stinging tentacles
If a sponge has plenty of food but cannot distribute it to all of its cells, what is the sponge missing?
Amebocytes
Gemmule
Collar cells
Flagellated cells that pump water into a sponge are called what?
Nematocysts
Mesoglea
Collar cells
Mesenchyme
Why don't planarians need circulatory systems?
They are so sessile that they use almost no energy
Their digestive system is highly branching through their body and they breathe through their skin
They have amebocytes that give them oxygen and food
What is the main mode of asexual reproduction in a planarian?
Gemmules
Regeneration - tears itself in half and grows replacement parts in each
Budding
What is the predominant mode of asexual reproduction in a sponge?
Testes
Gamete
Regeneration
Budding
A sponge feels hard and spiney. Does it contain spicules or spongin?
Spicules
Spongin
In a dissected earthworm, you see a nerve cord with ganglia at each segment right next to a long blood vessel. Is the blood flowing towards the anterior or the posterior in this blood vessel?
Posterior
Anterior
Neither
What similarities exist between the hydra's sexual reproduction and the earthworm's? What differences exist?
Earthworms cannot reproduce by budding but a hydra can
Both are hermaphroditic (male and female parts in one body)
An earthworm can reproduce by tearing itself apart, but a hydra cannot
What benefits do earthworms give the plants in the soil that they inhabit?
Select all that apply.
Loosens the soil allowing air and water to filter in
Mixes the nutrient-rich topsoil with mineral-rich soil below
It kills organisms that eat the plants' roots
If an earthworm's mouth is fully functional but it cannot ingest soil, what organ is malfunctioning?
Cuticle
Pharynx
Esophagus
What series of strongly-muscled vessels link together the dorsal and ventral blood vessels in an earthworm?
Aortic arches
Ganglia
Radula
What process will stop if the earthworm's cuticle dries up?
Respiration
Reproduction
Circulation
I will study the anatomy of the earthworm EXTENSIVELY before the exam.
True
False
An earthworm's seminal vesicle is empty but its oviducts are full. Has the earth worm mated yet?
Yes
No
