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!)

No. Sponges are animals and animal cells do not have a cell wall.
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.
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!
No sponges lack organized multicellular organs, such as nerves and muscles.
Sponges are animals of the phylum Porifera
Collagen
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.
No. Sponges are animals, which are heterotrophic.
Spicules provide structural support.
Sponges are animals of the phylum Porifera.
Sponges are animals of the phylum Porifera
why are collar cells important in classifying sponges as animals
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.
