Quizplus · Accepted Answer

Gastrulation results in the formation of a trilaminar embryo consisting of ectoderm, endoderm, and mesoderm. This process involves the invagination of cells and the formation of the germ layers, which give rise to all the tissues and organs of the body. The bilaminar embryo consisting of the epiblast and the hypoblast is present before gastrulation, and is transformed into a trilaminar embryo through this process. Therefore, options A, B, and E are incorrect. Option C is partly correct in describing the resulting gastrula as trilaminar, but does not specify the nature of the three layers.
