cnidaria
what is an example of a medusa
sea jellies
water exits the sponge through an opening called what
osculum
what are 3 examples of bivalves
clams,muscles,oysters
is phylum porifera vertebrates or invertebrates
invertebrate
how is the nematocyst "fired" in a cnidarian
contact with the cnidocil (trigger) fires the nematocyst
what are 3 examples of polyps
Sea Anemone Coral Sea Pen
which type of specialized sponge cell is responsible for straining food from the water
daily triple
collar cells (choanocytes)
what are the 3 classes within phylum mollusca
cephalopod,bivalve, and gastropod
is phylum echinodermata vertebrate or invertebrates
invertebrates
what does the name porifera mean
"pore bearing"
do cnidarians have nematocysts and if so what does it mean
Cnidarians have nematocysts- which are stinging cells
what are the small holes that are on the outside of the sponge called
ostia
what are the body structures and what are they for
daily double
Body Structures:
Cephalo = Head
Pod = Foot
Mantle = Body The main part of the body that contains the organs It’s a thin layer of skin In some Mollusks it can produce a hard shell
Radula = Tongue Contains teeth-like structures Used for scraping food
are mollusks vertebrates or invertebrates and what does it mean
Mollusks are invertebrates.
Their body is soft but they contain hard structures within their body. They do contain organs.
what level of organization are members of the phylum porifera at?
cellular
what are the 2 body forms and what do they look like ?
double or nothing: if you answer both questions right you get 800 points if you get the second question wrong you lose 400 points and the other team gets 400 points automatically and the other team can answer and if they get it write they get 800 points and if wrong the lose 400
Polyp:Tubular Sessile
Medusa:Bell Shaped Free swimming
how long ago do some of their fossils go back to
over 600,000,000 years ago
what are 3 examples of gastropods
conch sea snails and sea slug
Is Chordata a vertebrate or invertebrate?
vertebrate
what special cells do sea anemones, jellyfish, corals and hydras have and what are they for
double or nothing: if you answer both questions right you get 800 points if you get the second question wrong you lose 400 points and the other team gets 400 points automatically and the other team can answer and if they get it write they get 800 points and if wrong the lose 400
cnidocytes stinging prey, defense
what are the 4 classes ? and what do they mean
If you get it right you can take away 200 from the other team at any time but only once points if you get it wrong you lose 600 and 100 your next turn
Anthozoa: This includes sea anemone, coral, and sea pen They appear to look like plants however they are really animals Only polyp phase Coral
They are hard because they build calcium shells around
themselves for protection They form and thrive in colonies Coral has a symbiotic relationship with an algae called
Zooxanthellae Symbiosis is when there is a relationship between two
organisms that they both benefit from Zooxanthellae releases oxygen and nutrient for the
coral Coral releases carbon dioxide for the algae
Scyphozoa: This class consists of true sea jellies They can be large and range in size Many travel in groups called shoals They alternate between the polyp and medusa phases Mostly in medusa phase They swim by relaxing and contracting muscle fibers
Cubozoa: Box jellyfish They are different than true jellyfish because: Their cube-like shape They have 4 evenly spaced clusters of tentacles Mostly Medusas
Hydrozoa: This class includes fire coral, hydroids, and siphonophores (portuguese man of war) This is the most diverse group of cnidarians They form large colonies Mostly polyps, some medusas
are porifera heterotrophs. and if yes what does it mean
yes
what are 4 examples of cephalopods
Octopus Squid Cuttlefish Nautilus
are cnidarians vertebrates or invertebrates and what does it mean
if you get this right you get an extra turn that you can use after any of your turns if you get it wrong you lose your next turn
Cnidarians are invertebrates
They contain tissues but do not have organs They do not have a head They have 2 cell layers, most complex animals have 3 cell layers
list and describe the three body plans of sponges
1. Asconoid - simple, 1 osculum/spongocoel
2. Syconoid - more complex, can have multiple oscula/spongocoel
3. Leuconoid - most complex, largest, multiple oscula/spongacoels
