Sponges may be tiny forms which are easily overlooked they large enough man to stand inside very unusual animals representing offshoot kingdom that evolved along its own lines separate from vast majority types. It may be that each unit comprising single osculum and surrounding tissue one individual sponge produced new individuals failed to separate completely. The assumption is that sponge tissue will not grow into regions of water where it finds insufficient food such too close other which have already removed from . In type syconoid sponges an additional layer of dermal tissue perforated by large pores covers the structure. The various spicule types of which there are many subtypes have not mentioned different skeletal roles within sponge body and present also depends upon species

All the other cells appear to be connected one another by cytoplasmic bridges though they may have rounded bodies making them resemble distinct . Amoebocytes have variety of functions including maintaining the mesogloea mesenchyme and removing foreign organisms debris from sponge body. Biochemicals called sponge factors are known be secreted by tissues when graft introduced if the strains incompatible then these will reduce adhesiveness of cells one another and unable stick fuse recipient

Archaeocytes ingest and digest food caught by the choanocyte collars transport nutrients to other cells of sponge. Gland cells may put out long strands to the sponge surface secrete slime. The amoebocytes are free to wander about sponge fall into two main classes lobopodous collencytes

The architectures shown above are all open in which water exits through large central spongocoel cavity. They typically have wavy contours strengthen connections between them by increasing surface area along which cells can fastened together. Left a model of an infaunal sponge. Traditional bath sponges not the artificial type have spongin skeletons and mineral spicules which gives them springy spongy texture ass Hexactinellids Glass consisting of lattice glasslike siliceous fibres. As this water flows through the sponge body food particles are filtered from it

Collencytes have slender branching pseudopods called filopods and may form syncytial network syncitium is group of neighbouring cells whose membranes are fused together continuous mass cytoplasm. Most sponges are of the leuconoid type as this permits to develop efficient water current and attain larger size filters food from more efficiently. The choanocytes work very much like group of organisms called may live as single cells multicellular colonies and are rather lacking pinacocytes mesogloea other packaging that make sponge body

In some sponges archaeocytes develop into gametes. Megascleres are larger and often mesh together form bulk skeleton microscleres smaller generally free in tissues . Sycon consumes. Sponges may smother and kill sessile animals as they grow including oysters. Choanocytes These distinctive cells line interior body walls of sponges

Sometimes individuals of the same species but growing different locations may show very shapes although each tends to adopt particular range . Archaeocytes are possibly cells and produce the sex as may choanocytes in some sponges . Individuality spongesMany are colonialmany tubes each bearing osculum vent may fused together at their bases form single mass
