Sponges are multicullular animal having 13 types of cells arranged in outer pinacoderm, inner choanoderm and intermediate mesohyl with 10 types of wandering cell each with specific structure and functions. They are neither derived from a common germ layer not share a functional similarity. For this reason they are considered as the republic of cells without tissue system of organisation.

What members of porifera are diploblastic?
Porifera (sponges) have no specialized cells. To be diploblastic animal phyla must have a minimum of two cell layers referred to as ectoderm and endoderm. The absence of these cell types make it impossible for any members of porifera to be diploblastic.
What are facts about porifera?
-has no tissues,organs, or an organ system. -sessile -asymmetrical -loose republic of cells ex. sponges are the most common that are found in the ocean
How does a porifera breathe?
porifera dont have lungs or gills so the oxygen diffuses straight into their cells
Is porifera eukaryotic or prokaryotic?
Yes, Porifera or sponges are eukaryotic because they have a nucleus and organs in their cells, they are unicellular but still very primitif.
How does porifera breathe?
First of all, porifera do not breathe: they respire. Oxygen diffuses through the cells
What is special about a porifera cell?
The thing that is special about these cells is in fact, nothing. hahahahahah
What are the characteristics of porifera?
Porifera are pore bearing animals . Pores include ostia and osculum . they possess choanocytes or collard cells .
Do porifera have nerve cells?
No , Poriferans lack typical neuron cells but they possess some neuron like cells which regulate flow of water . These cells are present around porosites .
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.
Why porifera is characterised by choanocytes cells?
choanocyte cells are the cells lining the inner side of the sponges tiny bodies. It plays an important role in material transportation in and out of the sponges.
Describe the phylum porifera?
The Phylum Porifera consists of the sponges. To make it into the porifera phylum an animal must have no true tissue. Some contain spicules, a skeletal element, and all contain choanocysts, a type of cell, which move water through the porous bodies of poriferas. Porifera also have totipotent cells, which have the cabalitity of changing into whatever type of cell is needed by the organism.
What other organisms are found in the category phylum 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.
