In most animals cells that carry out the same function form structures called tissues. An organ is a group of tissues working together for a common function.
Sponges can be said to show some cell differentiation (and therefore have tissues). The porifera (the phylum containing sponges) are some of the most ancestral animals on the planet and only have two cell types. One makes up the soma (the body) and the other the germ line (a reproductive system). Interestingly, these cells have the ability to self-recognise which was important in the evolution of multicellularity. So, if you put a sponge through a blender if will eventually rearrange itself back into its original form. (Please don't try this with your pet hamster - it definitely won't work!)

What cells of all animals are organized into structural and functional units called tissues EXCEPT for the?
sponges!
What structural protein found in all sponges is?
Collagen
Do the cells of a sponges have cell walls?
No. Sponges are animals and animal cells do not have a cell wall.
Three kinds of animals that use filter feeding to get food?
Filter feeders are also known as suspension feeders and are most commonly aquatic animals or birds. Three examples of filter feeding animals are flamingos, clams, and sponges.
Is a sponge living?
Yes a sponge is or Porifera, are simple-celled, filter feeding animals, they are not plants. As a mater of fact you can still get real sponges for washing if you look in the right places. Just Google "sea sponges" if you want too see more on this subject,

sponges!
Which animal phylum has the lowest structural organisazation?
The phylum Porifera, which includes sponges, has the lowest structural organization among animal phyla. Sponges lack true tissues and organs, instead consisting of loosely organized cell layers that perform basic functions like feeding and reproduction.
Do sponges have nerves?
No sponges lack organized multicellular organs, such as nerves and muscles.
What is sponges plants or animals?
Sponges are animals of the phylum Porifera
What structural protein found in all sponges is?
Collagen
Are sponges autotrophs?
No. Sponges are animals, which are heterotrophic.
What are the functions of spicules in sponges?
Spicules provide structural support.
What species are sponges?
Sponges are animals of the phylum Porifera.
What group are sponges divided into?
Sponges are animals of the phylum Porifera
Why are collar cell important in classifying sponges as animals?
why are collar cells important in classifying sponges as animals
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.
Are mushrooms and sponges fungi?
Mushrooms and toadstools are examples of fungi. Sponges are animals of the phylum Porifera. In biological terms, fungi form a kingdom. Plants have a separate kingdom. Animals have a separate kingdom.
