Which phylum doesn’t have germ layers
1
endoderm and ectoderm
undifferentiated + non cellular–>jelly like parenchyma –> mesoglea

segmentation
-aka
- what is it
- example
- metamerism
-body externally or internally or both divided into segments with serial repetition of some organs
AAC annelida arthropoda chordata
notochord
-rod like structure ________{origin}
derived
present in __________
- in hemichordates?
mesodermally
chordates
they have stomochord which isnt true notochord in the collar region
