How do nutrients and oxygen move throughtout the body of phylum porifera?

Answer 1

This is an interesting question. Apparently, Porifera, i.e, sponges do not have any digestive system. They have their specialized colony of animal cells doing it for them. The water flowing system in the porifera plays an important role. The small body of the porifera can take in particles and microbes which are less than 50 micrometers. They enter through ostia into the body that is lined by a specialized type of cells known as choanocytes. There are microville that absorb the nutrients for the growth of porifera.

There are a group of porifera which have evolved into carnivorous. They captivate and digest the crustaceans of size about 1 mm. They produce some kind of threads that capture them and roll around them to digest their prey.

Answer 2

The beating flagella inside the porifera move water around, and the flowing water flows oxygen and food particles through the pores.
