Question

Quizplus · Accepted Answer

Gastrulation is the process by which the three germ layers (endoderm, mesoderm, and ectoderm) are formed, which eventually give rise to all the organs and tissues of an organism. Therefore, option D is the correct answer. Option A is also partially correct as it describes the eventual outcome of gastrulation. Option B is referring to implantation which occurs before gastrulation. Option C refers to the initial step of gastrulation, but it does not encompass the entire process.
