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.
That would be sea sponges, because they are covered with "pores"... "Pores", "porifera", see the similarity?
The sponge.
I think sponges are (:
dogs and cats
a sponge
basically all sponges
SPONGES
Sponges found in the phylum Porifera.
Ostia are incurrent pores, found on organisms in the Phylum Porifera (aka sponges). Basically; they are body openings on sponges.
Te organisms found in the phylum chorodata are sea squirts and vertebrate animals.
Neofibularia nolitangere or the "touch-me-not" sponge (found in the bahamas) can cause sever skin rash/burn/numbness if it comes in contact with your bare hands
The phylum chrysophyta is green algae. They can be found on any body of water; ponds, lakes, creeks, streams, rivers, etc.
Animals who are in the phylum porifera usually live in marine and aquatic environments like the ocean because they are sponges.
They can be found in an Animal and Plant cell.(humans fall into the animal category)
Earthworms belong to phylum Annelida, they are tube structured organisms living in soil. They have segmented body. Sponges belong to phylum Porifera, they are marine dwellers and they are sessile organisms found in beautiful colours in ocean floor.
Phylum PoriferaClass CalcareaOrder ClathrinidaOrder LeucosoleniidaOrder SycettidaOrder LeucettidaClass HexactinellidaClass DemospongiaeOrder HaploscleridaOrder PoeciloscleridaClass SclerospongiaeWith about 5000 species known across the world. Sponges are primarilymarine, but around 150 species live in fresh water. Sponges havecellular-level organization, meaning that that their cells arespecialized so that different cells perform different functions, butsimilar cells are not organized into tissues and bodies are a sort ofloose aggregation of different kinds of cells. This is the simplestkind of cellular organization found among parazoans.
Confirerophyta is the phylum where taxol was originally found.
