Question

Explain the germ layer system of phylum porifera.

Open in App
Solution

Dear student,
The production of germ layers takes place through gastrulation process in the embryonic development. There are three germ layers : ectoderm, mesoderm, endoderm.
Phylum porifera doesnt have any true germ layers as gastrulation process doesnt occur in these organisms.
