Most sponges are immobile creatures and depend on their ability to pump water through their bodies in order to make a living. The advantage, of folded or convoluted walls, is enhanced efficiency for the sponge's ability to gather food and oxygen, and to rid itself of waste. This configuration maximizes the sponge's pumping capacity while, at the same time, slowing the flow of water past each cell. This amazing adaptation allows the sponge to take in more nutrients (pumps more water) while giving it more time (slowing the flow past each cell) to exchange food, oxygen, and waste.

Yes. they have two germ layers - or a two - layerd body wall. The epidermis and gastrodermis. Actually sponges lack true tissues and are therefore not diploblastic.

No, the cells of sponges do not have cell walls. Instead, sponge cells are held together by a gelatinous extracellular matrix called mesohyl. This allows for flexibility and mobility of the sponge's body.
Choanoflagellates are a group within kingdom Protista that are thought to be the closest living relatives to sponges. This is based on similarities in cell structure and genetic sequences between choanoflagellates and sponge cells.
ADH promotes water reabsorption through the wall of the collecting duct in the kidney by increasing the permeability of the duct to water. This helps regulate water balance in the body by allowing the reabsorption of water into the bloodstream.
There are some advantage,
The paint becomes part of the wall.
The wall of the urinary bladder of a fetal pig is a sack like organ located by the umbilical cord. When relaxed the walls appear to be folded.
distributes loads across the wall
try using a srub brush with soap, arm and hammer sponges, soap wipes (wipes) :)
Fold mountains are formed from the collision of continental tectonic plates. Since neither plate subducts under the other, the colliding plates wrinkle and fold like a rug being pushed into a wall.
