Animal tissues develop from embryonic germ layers. Triploblastic animals have three germ layers (ectoderm, mesoderm, and endoderm) and three basic body plans related to body cavities (acoelomate, pseudocoelomate, and coelomate). Select the three statements that are true. To review the germ layers and the terminology associated with body cavities, see the Hints.1) A diploblast has no mesoderm.
2) In a coelomate, the tissue lining the inner side of the body cavity arises from the same germ layer as the lining of the digestive tract.
3) A pseudocoelom has the same functions as a true coelom.
4) The digestive tract of a coelomate functions as a coelom.
5) In a pseudocoelomate, the tissue lining the inner side of the body cavity arises from the same germ layer as the muscles.
6) An acoelomate triploblast has no endoderm.
7) In a coelomate, the tissue lining the inner side of the body cavity arises from the same germ layer as the tissue lining the outer side of the body cavity.
