Title: In triploblastic animals, the inner lining of the digestive tract is derived from____? Post by: rivera5454 on Jul 17, 2012 I understand that the difference between diploblastic and triploblastic animals is the one extra germ layer, the mesoderm. But I was under the impression that the endoderm forms the gut. Here are the answers I have to choose from:
A) Ectoderm B) Mesoderm C) Endoderm D) Pseudocoelom E) Coelom Title: In triploblastic animals, the inner lining of the digestive tract is derived from____? Post by: lgdaniels on Jul 17, 2012 Body covering - (from ectoderm)
Digestive tract - (from endoderm) Tissue layer - lining coelom internal organs - (from mesoderm) Coelomates such as annelids have a true coelom, a body cavity completely lined by tissue derived from mesoderm So. correct answer is C. endoderm |
