no. they have tissue like stuff but not true tissue.

∙ 9y agoNo, they for sure do not. Sponges have a channel like interior that capture food particles when water flow through it. The food is digested by specialized cells.

What are the primary characteristics of animals that are not exhibited in sponges?
Sponges do have some differentiated cells that have different functions but they don't have true tissues like all other animals and plants do. Even though they're included in the Animal kingdom they also symmetry, which most other animals have.
What class is a sea sponge in?
Sponges are classified as "animals" of the phylum Porifera. However, they have several characteristics in common with plants. Most have no specialized tissues or organs, and depend on the flow of sea water to provide oxygen and nutrients.
Which group of animals has tissues but no organs?
It is Phylum Porifera. The porifierans are multicellular organisms but don't have tissues or orgrans. Example: Scypha, Leucosolenia, Euplectella etc.,
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.
What are some examples of hexactinellida sponges?
Glass sponges
Which knigdom can develop tissues?
All animals except sponges
What phylum do sponges blong to?
Sponges belong to the phylum Porifera. They are multicellular aquatic animals that lack tissues and organs.
What can you about an organism with no tissues?
A unicellular organism lacks tissues, organs, and organ systems.
What does it mean when sponges have no true tissues?
Similar cells do not cooperate together.
What level of organization in missing in sponges?
tissues, organs, and organ system
What is the only animal phylum that does not have tissues and symmetry?
The phylum Porifera (sponges) is the only animal phylum that lacks true tissues and symmetry. Sponges are simple multicellular organisms with specialized cells, but they do not have tissues that are organized into distinct structures like other animals. Additionally, sponges exhibit asymmetry rather than bilateral or radial symmetry found in other phyla.
What does body organs do sponges have?
sponges have no cells which means no tissues and that means no organs because of what the cycle is there would not be any organs in the body of a sponge
What primitive group of animals has no true tissues and no specific distinct shape?
Sponges
Do sea sponges have a diploblastic or triploblastic body organization?
spoges are diploblastic because they have radial symmetryone's having rad. sym. are diplo.and one's having bilateral are triploblasticThis is a true statement, but what we find in animal biology is that there are exceptions to most of the rules. Sponges, or the phylum Porifera do not have true tissues. They are metazoa at their cellular grade of construction, not eumetazoa. If you look at phylogenic tree, you will see that sponges are not directly related to cnidarians, which are radial symmetric and diploblastic. Some sponges are radial symmetric, however the class of sponges, demospongiae, have many species of sponges which have leuconoid body-plans, which are asymmetrical. These are mostly freshwater sponges. So therefore, sponges are not triploblastic or diploblastic, they are neither since they possess no true tissues.
What kingdom and phylum do sponges belong to?
Sponges or poriferans are animals of the phylum Porifera.Sponges are divided into the following classes mainly according to the compositions of their skeletons:1.Calcarea2.Glass sponges3.Demosponges
How many embryonic tissues does a sponge have?
Sponges have two germ layers therefore they are diploblastic.
Name the only type of animal that lack groups of cells that form tissues?
The sponges.
