Contractile myocyte cells are present around osculum, a large pore for throwing out water from spongocoel.

Then there are spongocytes which secrete skeletal material. Create a diagram of an adult sponge body plan that shows how sponges obtain food. Ectodermal or outer layer of sponge body is made up of pinacocyte cells. There are several other cells in Porifera. The pore through which water flows in is called ostium (singular). Each porocyte allows water to flow inside the spongocoel from surrounding aquatic habitat. Porocytes are unique, elongated, tubular cells. Digestion is also intracellular, taking place within choanocyte. These cells capture microcopic food particles. Choanocyte also has a collar made of microvilli.
The flagella help in creating a unidirectional flow of water around the body of sponge. Moreover choanocytes also give rise to germ cells.Ĭhoanocytes are flagellated cells which line the spongocoel and form the so called 'choanoderm': the layer represents endoderm of a diploblastic poriferan organism.
