What is a of a sponges body?
It has two cell layers.
Are sponges diploblastic?
Yes. they have two germ layers - or a two - layerd body wall. The epidermis and gastrodermis. Actually sponges lack true tissues and are therefore not diploblastic.
Which phyla have only two tissue layers?
The answer is probably sponges.
What do you mean by diploplastic?
Diploblastic is generally referred to as "having a body derived from only two embryonic cell layers (ectoderm and endoderm, but no mesoderm), as in sponges and coelenterates".
How many embryonic tissues does a sponge have?
Sponges have two germ layers therefore they are diploblastic.
Do sponges have segmented bodies?
Rather than calling it as having segmented body, it is more apt to say they have poriferous body that is body with many pores. Sponges are collection of microscopic animals. The body of a sponge has two outer layers separated by an acellular gel layer called the mesohyl. The gel layer has calcium carbonate or spongin protein that gives it the rigid structure.
What are the two main functions of spikes on sponges?
To protect the sponge's body.
What is the name for the space between the two layers of the mesoderm?
The space between the two layers of the mesoderm is called the coelom. It is a body cavity that forms during embryonic development and gives rise to various organs, such as the heart, lungs, and digestive system.
What is the scientific name for the mollusk sponge?
There is no such nomenclature. Mollusks and sponges are two forms of invertebrates.Some sponges, such as Myxilla incrustans form symbiotic relationships with some mollusks (i.e scallops).

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 Poriferans?
"Poriferans" is the scientific term for sponges, members of the animal phylum Porifera, which means "pore-bearer" in Greek. Sponges are the simplest animals known. Unlike all other animal phyla, which have two or three-layered body plans (diploblastic or triploblastic), sponges have only a single body layer (monoblastic), and no true tissues. They have no appendages and no ability to make any movements, lacking muscle tissues. Sponges are exclusively aquatic.
