Sponges are similar to what might have been the ancestor of animals: colonial, flagellated protists. Although they have specialized cells for particular functions, they lack true tissues in which specialized cells are organized into functional groups. Sponges appear to represent an early stage of multicellularity in the animal clade. The sponges and the cnidarians represent the simplest of animals.

Invertebrates include a huge diversity of animals, millions of species in about 32 phyla, which we can just begin to touch on here. Although in general we are most familiar with vertebrate animals, the vast majority of animal species, about 95 percent, are invertebrates. The kingdom of animals is informally divided into invertebrate animals, those without a backbone, and vertebrate animals, those with a backbone. Describe the organizational features of cnidarians.

Describe the organizational features of the simplest animals.

So this is how a new fledgling look like.By the end of this section, you will be able to: They have they are both legislated having structure like this having structure like this. So these are the sponges obviously because we knew that because kind of legislator and sponges show very much similarity. So next is which film is the ancestor of the queen of legislators. So there are in current canals and the ex current canals to do so in current canals in current and the excrement canals which in current means that inside so they take the water inside and excrement expel the water outside. So next is what creates grant or flow of water through the sponge. So I hope you understood the first question will. Hill spongy Ozil is the central cavity, central cavity after entering the central cavity, it will be removed through the SQL um It will be removed through the or skill. This is the body and they have these small pores. So water enter through the small pour it. Water and um sponge moved through the moving water because they carry water is very important because water carry food food as well and it removes the it removes the waste as well waste as well.

So the correct option is um correct option is d because water entered through the in the body cavity through the SQL um and flow through the body votes so Osk Yalom is very important to ask you um plays an important role. So peripheral indicates that they have poor and poor, does all the function of transport of water and food. So what are sponges? Sponges belong to the phylum peripheral. Hello students of this question is about how water and food moves through the body of sponge.

Move water through sponge
