Compare the structural differences between Porifera and Cnidaria.

All right, this questions asking you to compare peripheral to Nigerians Peripheral is a fancy way of saying sponges, and I'd Erian's. There's lots of types of them, but you're probably familiar with, like jellyfish. And so the main difference between them are the cells they use to get food. So over here with sponges, water will come through this opening right here, and we'll travel through this canal over this cavity. I guess I should say. And within this cavity are these little cells called Joanna Sites. And these co ana sites have these little things on the end of them called Flow Gela. And if you've heard of flu jello before, you know that flow Gela are used for movement. And so what will happen is that water will run through this cavity right here and the flu. Gela will will move that allows that water to run through it, and so will circulate that water, and any nutrients in the water will stick to the cavity from a mucus that thes clan asides secrete. And so basically those nutrients get stuck there, and then the sponge is able to digest those nutrients, which allows it to survive um now 90 area have a lot of things in common with peripheral, but the one distinct difference they have is that instead of Qana sites, they have something called night of sites and night asides contain something called Nomad assists. And I forgot to put the on a year saving. Get that. So know Mattis Ists. Are these, um, barbs? Basically, that can, um, secrete a toxin. And so, just like over here but sponges, water will, and water will come through the canal oven idea and not dairy, can have two forms. They can look like this one over here, which is like we're like a jellyfish where they can have one over here that's more immobile. It's called a polyp. This first one's called a medusa. Anyway, water will come through these canals, and it will circulate and, um, organisms that maybe within the water, if they come into contact with these non decides, then the night asides will react and release a toxin that will basically paralyze or kill the organism so that the Nigeria can digest it. And so they do have a lot of features in common. But the main difference between them are the types of cells that each of them use to, um, to acquire nutrients in order for survive

Here we have a list of the grips of investments and we're going to be matching these Teoh um, different descriptions. So we'll have a tubular goats and to see their Selim be spiny skin. See the simplest organ systems the most support in their cemetery. A a jointed x of skeleton f mantle over the body mass. He is of the segmented worms on the H 10 schools with stinging cells. So let's let's Matthews up. Starting the mechanisms eso econ in terms you guess from a skin. I'm sorry. DSM is skin econo spinal e u s. It is B spiny skin. Next we have the mosques. Eso molluscs are defined by f Their mantle is over the top of their body mass way have sponges. Sponges are d lots of pause though symmetry area simple organisms have been that Aaron's Nigerians are defined by that stinging cells with other sites. So they're going to be a church. Have flat wimps and flatworms are extremely simple. This was what organs go see Maybe around wolves the grounds wombs have a a pseudo Selim on a tubular guts season like imitates way have the analysts on? Let's RG there'll be segmented worms. Earthworms, which leaves us with offer parts, is having he jointed exoskeletons. So we've matched up all of the organisms to descriptions.

Everyone suffers question. We can start with the mollusc and that goes with which is the option telling us that it has a mental over the body mess, which it does, and that is actually what makes its shell because it secretes calcium. Next on the list, we have a kind of germs, and those are stark fish, and they have two feet to move, but they also have a spiny skeleton, which are called little obstacles. And so that is why this option would go with H for a question. Our next organism is the sponges, and these have no organs. So they just felt your feed as water goes through them and they'll capture nutrients, and they also have no tissues. So that is why this option will go with D, which says no tissues and filters out, um, food. So our next option, the Nigerians, which are jellyfish, uh, actually goes with option B because they have little, huh? Stinging cells known as needle sits sites and these are the ones that have new mad assists on them, which protect them from pray by singing. So our next option are the flatworms, and this would be see because they have a very simple and incomplete gut. It's about a C. Next, we have the roundworm, which has a pseudo called, Um so it has a complete gut, and that would be a and then I'll school here. Still or next is analysts and analysts are segmented worms. And that is why, in his option, G and all we have left is arthropods, which we know how are the only ones with a hopes are fix that. So are throw pods with the exoskeleton, and that is option E. That is the end of our question.

Mhm. Let us complete the sentence. Animals consider dipole plastic are in the blank fila. Let us discuss dipole plastic organisms dip a plastic. Animals are organisms which developed from such a blast to and including the area antenna fora formerly grouped together in the phylum colon Terada. But later understanding of their differences resulted in there being placed in separate villa. The endo dermal allows them to develop true tissue. Let us go back and fill in the blank. Animals. Consider dipole plastic are in the Nigeria and kenya, fora fila.
