The main function of spongocoel is nutrition. Water enters into this cavity by pores except the largest pore called osculum, from which, they separate food and then water leaves.

What is spongocoel and its function?
A spongocoel (/ˈspɒŋɡoʊˌsiːl/), also called paragaster (or paragastric cavity), is the large, central cavity of sponges. ... amoebocytes – motile cells that perform various digestive functions within the sponge by transporting and/or storing food and excreting waste.
What do you mean by spongocoel?
Definition of spongocoel
: the internal cavity of a sponge discharging by way of the osculum.
What is the main function of a Choanocyte?
Choanocytes join together creating the choanoderm, where they perform two major functions. The first is to create a flow of water and the second is to capture food items as they pass by these cells. The flow of water is initiated through the coordinated beating of flagella.
What is the function of sponge?
As water filters through a sponge's porous exterior, the sponge gains some motion, receives food and oxygen, and dispels waste. Inside the sponge, tiny hairlike structures called flagella create currents to filter bacteria out of the sponge's cells and trap food within them.
What is spongocoel in biology of Class 11?
Spongocoel is a large, central cavity of sponges from where water enters. The spongocoel is surrounded by a lining of cells called choanocytes, containing a central flagellum that is surrounded by microvilli.
What is the function of spongocoel in porifera?
As we already mentioned, a spongocoel is the large, central cavity of sponges (Porifera). The main function of spongocoel is nutrition. Water enters into this cavity by pores except the largest pore called osculum, from which, they separate food and then water leaves.
Which cells are situated around spongocoel?
The spongocoel is lined by the flattened collar cells or choanocytes. Spongocoel opens outside through a narrow circular opening called as osculum located at the distal end and it is fringed with large monaxon spicules.
Where can spongocoel be found?
Spongocoel is found in phylum Porifera. porifera means"pore-bearing" & refers to numerous pores and channels that permeate a sponge's body. Ostia(ostium) or incurrent pores lead into a cavity, these internal cavity is called the paragastic cavity or spongocoel. Spongocoel is the large central cavity of sponges.
Do all sponges have a spongocoel?
There is no real spongocoel in leuconoid sponges. One feature that is common to all three types of body plan is the presence of a holdfast at the base of each animal. The holdfast is what the sponge uses to anchor itself to a solid surface, such as a rock.
What is the function of choanocyte cells in sponges?
The feeding chambers inside the sponge are lined by choanocytes (“collar cells”). The structure of a choanocyte is critical to its function, which is to generate a directed water current through the sponge and to trap and ingest microscopic food particles by phagocytosis.
What is the function of Mesohyl?
The mesohyl acts as a type of endoskeleton, helping to maintain the tubular shape of sponges.
What is the evolutionary significance of choanocyte cells in sponges?
Sponges in particular have often been viewed as living surrogates for early animal ancestors, largely due to similarities between their feeding cells (choanocytes) with choanoflagellates, the unicellular/colony-forming sister group to animals.
Which of the following cells line the spongocoel and the canals of sponges?
Pinacocytes line the spongocoel and incurrent canals.
Which body type does not have a spongocoel?
Leuconoid sponges lack a spongocoel and instead have flagellated chambers, containing choanocytes, which are led to and out of via canals. Physiology: Sponges have no real circulatory system, however the water current is used for circulation.
What is the function of Spongin and spicules in a sponge?
Besides supporting sponge cells, spicules can help larvae stay buoyant while in the plankton or reach the bottom at settlement, enhance reproduction success, or catch prey.
