Zoology - Sponge
Glass-like, sharp-pointed structures that make up the frame of some sponges
Spicules
are choanocytes and collar cells the same thing
YES
Carry nutrients from the choanocytes to other body cells
amoebocytes
can move through the mesohyl
amoebocytes
can transform into oocytes
amoebocytes
what can spicules be made of
calcium carbonate, silica
pinacocytes
cells that hold the mesohyl inside the sponge
also known as collar cells
choanocytes
have a flagellum that whips back and forth to create a water current through the sponge
choanocytes
have microvilli that trap food particles
choanocytes
what protein holds the cell of a sponge together
collagen
whats the role of the sclerocyte
compromise the internal skeleton
Triploblast or diploblast
diploblast
four survival requirements of a sponge
feeding, excretion of waste, intake of oxygen & removal of CO2, reproduction
the base that anchors a sponge down
holdfast
what happens when a sponge passes through a sieve
its cells are sperated
Jelly-like substance between the outer and inner cell layers of a sponge
mesohyl
filled with spicules, sclerocytes, amoebocytes, and oocytes
mesohyl
how do sponges maintain their diploblastic form from the embryonic stage until adulthood
mesohyl
what can the amoebocytes do that other cells can´t
move through the mesohyl
egg cells
oocytes
large opening on the top of the sponge
osculum
where wastewater exits a sponge
osculum
pores of a sponge
ostia
where water containing nutrients and oxygen enters a sponge
ostia
whats found in the mesohyl
other structures and cells
how many different species of sponges are there
over 9,000
contract and relax to control how much water enters pore cells
porocytes
the kin"cells of a sponge
porocytes
create spicules
sclerocytes
made of calcium carbonate or silica
spicules
soft and flexible protein that makes up the frame of some sponges
spongin
the substance that makes natural bath sponges soft and squishy
spongin
what 2 substances make up the frame of a sponge
spongin, spicules
large central cavity in a sponge
spongocoel
other then feeding what other function does the pumping of a sponge have
there sex life
how do choanocytes power the pumping action of a sponge
there whip-like flagellum
how do amoebocytes assit the choanocytes
use the energy from food to move
what is crucial for a sponge to survive
water flow through the body
