sponges are made up of individual cells. I dont know about colentrates. They just are what they are. sponges also don't move while coelenterates do.
Segmented worms are more complex that coelenterates because their bodies are made up of three layers of cells, rather than two layers like for coelenterates. Each layer of cells is filled with specialized tissues and organs.
Yes they do :)

They were more advanced because they had more medical people and were much more advanced in technology.
Squid are considered more advanced than clams.
Sponges in the ocean can live up to 200 years old. They are primary produces and give off more oxygen than they take in.
osculum - a large opening in a sponge through which water flows out of the sponge. Sponges may have more than one oscula.
Round worms belong to phylum Ascelminthes (nemathelminthes) ,a higher phylum than sponges (poriferans) and coelenterones.Round worms are bilaterally symmetric.which is considered as a superior quality.Also they are triploblastic and has a well developed muscular pharyx.Sexual dimorphism is also seen in round worms.
Sponges retain moisture and become a breeding ground for bacteria. Studies have shown that a kitchen sponge can be more than 200,000 times dirtier than a toilet brush.
Red is more advanced than orange and actually purple is more advanced than red.
