choanocyte cells are the cells lining the inner side of the sponges tiny bodies. It plays an important role in material transportation in and out of the sponges.

What are the characteristics of porifera?
Porifera are pore bearing animals . Pores include ostia and osculum . they possess choanocytes or collard cells .
Do sponges or cnidarians have a gastovascular cavity?
No, they are from the Phylum Porifera.
What body type does phylum porifera have?
porifera is a multicelullar organism ,this has been a great achievement for these animals ,they have a body wall that is three layered namely epithelium this the outer part serves for protection ,mesohyale middle part contains amoebocytes which help in transportation of food and gastrodermis has the choanocytes which are the feeding cells 'collar cells' hope it helps sydney 3rd born
What name is given to the food-trapping cells of sponges?
Choanocytes
What is Porifera made up of?
They are supported by a skeleton made up of the protein collagen and spicules, which may be calcareous or siliceous, depending on the group of sponges examined. Skeletal elements, choanocytes, and other cells are imbedded in a gelatinous matrix called mesohyl or mesoglea
How do nutrients and oxygen move throughtout the body of phylum porifera?
This is an interesting question. Apparently, Porifera, i.e, sponges do not have any digestive system. They have their specialized colony of animal cells doing it for them. The water flowing system in the porifera plays an important role. The small body of the porifera can take in particles and microbes which are less than 50 micrometers. They enter through ostia into the body that is lined by a specialized type of cells known as choanocytes. There are microville that absorb the nutrients for the growth of porifera. There are a group of porifera which have evolved into carnivorous. They captivate and digest the crustaceans of size about 1 mm. They produce some kind of threads that capture them and roll around them to digest their prey.
Do sponges have specialized cells?
it has no muscles thats how it can function
How does a porifera breathe?
porifera dont have lungs or gills so the oxygen diffuses straight into their cells
What is the function of choanocytes in reproduction of sponges?
Those cells include a single flagellum that surrounded by a contractile collar of microvilli. The choanocytes are responsible for moving water through the sponge and for obtaining food.
Are choanocytes significant to a fundamental process for sponges?
The choanocytes move water through the sponge, similar to a digestive tract in higher order mammals. The choanocytes are the primary system for allowing nutrients to be absorbed by the sponge.
What are the specialized cells that use flagella to move a steady current of water through a sponge?
Choanocytes
Where is collar cell found?
Choanocytes (also known as "collar cells"). Choanocytes are found dotting the surface of the spongocoel in asconoid sponges and the radial canals in syconoid sponges, but they comprise entirely the chambers in leuconoid sponges.
