Question

Quizplus · Accepted Answer

The process of forming the germ layers is called gastrulation, which involves the movement and reorganization of cells in the blastula stage embryo to form the three germ layers: ectoderm, mesoderm, and endoderm. Meiosis is a process of cell division that produces gametes with half the number of chromosomes as the parent cell. Somite formation is the process of segmentation in vertebrate embryos that gives rise to the vertebrae and other repeat structures. Blastulation is the formation of the blastula, a hollow ball of cells in the early stages of embryonic development. None of these processes directly contribute to the formation of the germ layers.
