Question

explain me from if in protostomia
Tell me fastly as you can please..............

Answer 1

Protostomian animals are the triploblastic animals. In which the cell are formed from the six spiral cleavages during their embryonic development the blastopore is firstly developed in to the mouth. They are determinate
So based on this they are divided into three sub divisions
1. Acoelomates
2. Pseudo ceolomated
3.schizocoelomates
---> a coelomates are the animals in which the body cavity is(the space btn ecto derm and the gut) is not filled with the fluid coelom and is lined by mesoderm . Instead of coelom it is filled with mesenchyma tissue the supply of nutrients from the gut to the body wall is very slow because there is very slight mobility
Ex planaria, facilo hepatic a.
-----> pseudo corporates are the animals in which the body cavity is filled coelom but not lined by mesoderm. The supply of nutrients and food is fast and efficient.
Ex nematoda
----> schizocoelomates in which the bodycavity is made up of splitting of pouches of archeotron that is pouches are formed on the gut. And is lined by mesoderm.the supply of food particles is fast and is efficient.
