kingdom animalia
-contains?
-des. of organisms in general
-cell-specialization
-cell interdependancy
-95% invertebretes
-vertebretes
phylum porifer
-literal meaning
-ex
"bore-bearer"
sponges
Characteristics of Phylum Porifer (5)
-where they live
looke like
size range
how they live
feeding
1. most are marine
2. look like raw liver when living
3. less than 1 in to 6 feet
4. sessile
5. obtain food by pumping water into their hollow tube-like body (filter feeding)
sponge wall
-mini des
-not true layers
epidermis of sponge wall
outside protective layer
middle layer of sponge wall
jelly-like
contains spicules
spicules
act as skeleton for the sponge, providing support
-made of protein with soften water
inside layer of sponge wall
contains collar cells with flagella
-water enters sponge through incurrent pore
-contain amebocytes
collar cells (choanocyte)
have flagella which set up currents to draw water in to sponge
amebocytes
pick up food and oxygen from water & distribute the nutrients to the rest of the sponge body
-pick up Co2 (wastes) so they can be carried through the excurrent pore
3 things amebocytes help with
reproduction
respiration
feeding
another name for incurrent pore
pore cell
another name for excurrent pore
osciulum
types of asexual budding in sponges (porifer)
budding
gemmules
Budding as asexual reprodution for sponges
groups of cells enlarge, break off, live separately & grow into an adult
-unequal cell division
gemmules
buds with hard protective covers & food-filled, which allow buds to survive harsh conditions before growing into an adult
sexual characteristics of sponges
-how (4)
-one more characteristic
hemaphroditic- but does not produce egg & sperm at the same time
-sperm enter through pore cells of sponge by collar cells
-sperm are picked up by amebocytes & carried to egg
-fertilized egg develops into larva
-larva swims out of sponge & becomes sessile & develops into an adult
regeneration in sponges?
can grow missing parts
the less complex, the more able to regenerate
sponges areprotists or animals?
link between colonial protists & animals
not one

Phylum Cnidaria
-ex
hydra, jellyfish, man-of-war
Class Hydrozoa
ex
hydra/man-of-war
Characteristics of Hydrozoa
a. freshwater vs. marine
b. layers
c.
-freshwater
-3 layers, 2 are true
1. extoderm (epidermis)
2. mesoglea (not "true" one)
3. endoderm (gastrodermus)
-basal disk
basal disk
-in what class
-des
in Class Hydrozoa
- produces sticky substance for attachment to rocks & plants
Nurtrition for Class Hydrozoa
-mouth opening with stinging cells (enidoctyes) which contain harpoon like (hematoysts) things that capture prey
-stunned prey is forced into the stomach cavity/gastrovascular cavity/coelenteron
-digestive enzymes break down food for absorption
-undigested food comes back out of mouth (2-way tract)
enidocytes
stinging cells in hydra (class hydrazoa)
hematoysts
harpoon-like spears that attack hydra's prey (class hydrazoa)
coelenteron
stomach cavity/gastrovascular cavity
Nervous system of Hydra (class hydrazoa)
body is surrounded by nerve cells, which form nerve net, which allows hydra to curl up in to ball when touched
Asexual reproduction of hydra (class hydrazoa)
budding
Sexual reproduction for hydra (class hydrazoa)
sperm swim to eggs
-hermaphroditic
-separate sexes
Portuguese man-of-war
-mini des
colonial
Class Seyphozoa
ex
jelly fish
body forms of jellyfish (class seyphozoa)
polyp
medusa
Polyp
def
ex
tube shaped body with a basal disk (sticky substance for attachment) at one end and tentacles at the other
-ex hydra, young jellyfish
medusa
def
ex
round or bell-shaped with tentacles hanging from underneath; free-swimming
ex adult jelly fish
when do cnidarians have these body forms?
have at least one of these body forms during their life cycle, most have both
planulae
larval form of Cnidarians (free-swimming)
Class Anthozoa
ex
4 des
ex- sea anemones, corals, sea fans
1. all are polyps
2. all are marine
3. largest group of Cnidarians
4. symbiotic association with dinoflagellates
not one
not one
sexual reproduction in sponges
-hemaphroditic
-sperm enter through incurrent pore by collar cells
-picked up by amebocytes & carried to egg
-develops larva which swims out of sponge and becomes sessile and turns into an adult
regeneration
sponges can grow missing parts
(the less complex, the easier it is to regenerate)
sponges are protists or animals?
sponges are considered a link between colonial protists & animals
