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.
Name some sponges?
Hexactinellida, Calcarea, Demospongiae, andSclerospongiaeTechnically, however, the Sclerospongiae are not considered sponges. They are very similar, but they are not the same. Like bats and birds who have both evolved the ability to fly but are not the same types of animals, Slerospongiae have evolved and became very similar to sponges, but they are not sponges.
Do sponges have tissues?
no. they have tissue like stuff but not true tissue.
Why are sponges considered to be primitive animals?
Sponges were first though to be plants because, at first glance, they appear to be so. They are immobile, have no appendages to speak of, and lack a nervous and circulatory system. What sets them apart from plants, however, are two main things. The first being that they are filter feeders; they siphon water through their bodies and specialized cells with cillia catch the food and transport it to speceialized cells to be digested, whereas the vast majority of plants make their own food. The second is that most sponges start out as free-swimming larvae that eventually settle down onto a solid surface and transform into the sessile soft-bodied creatures we know as sponges.
Similarities and differences of real sponge and synthetic sponge?
Synthetic sponges are made of cellulose and have a similar appearance to a real sponge. Genuine sponges are multicellular animals with no similarities with a synthetic sponge except that their exoskeletons can be used to wash cars, etc.

Why are sponges classified as an animal?
Because no other animal has anything like collar cells..
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.

What organisms are found in porifera?
Porifera are sea sponges. They have no symmetry (asymmetrical) and they are one of the most basic forms of life. They have a 2 cell layer wall made of collar cells, spicules, amoeba like cells, and a layer of epidermal like cells. The spicules and the amoeba like cells are in between the layer of collar cells and epidermal cells. Sponges also have pores throughout their structure. Porifera include freshwater sponges as well of marine varieties. Freshwater sponges are common although not obvious. Frequently they are green in color due to included algae.
