WebSponges constitute the phylum Porifera, and have been defined as sessile metazoans (multicelled immobile animals) that have water intake and outlet openings connected by chambers lined with choanocytes, cells with whip-like flagella. [18] However, a few carnivorous sponges have lost these water flow systems and the choanocytes. WebWhile sponges lack defined organ systems, the tissue is composed of pinacocytes and choanocytes, two types of cells on the sponge surface. [8] In terms of structure, large branching erect sponges are prone to toppling during storms, while smaller sponges remained higher in biomass after storm events.

WebChoanocytes (“collar cells”) are present at various locations, depending on the type of sponge, but they always line the inner portions of some space through which water flows (the spongocoel in simple sponges, canals within the body wall in more complex sponges, and chambers scattered throughout the body in the most complex sponges). WebSponges have three body types: asconoid, syconoid, and leuconoid. Asconoid sponges are tubular with a central shaft called the spongocoel. The beating of choanocyte flagella forces water into the spongocoel through pores in the body wall. Choanocytes line the spongocoel and filter nutrients out of the water. What are the two body layers of sponges? Web1. Choanocytes (= collar cells) probably the most distinctive and most important of sponge cells each collar cell has a flagellum surrounded by a sieve-like collar that acts as a strainer “collar” is made of microvilli and microfibrils the flagellum beats to draw the water currents into the sponge and then to strain particles jessica padgett
