When does the Organogenesis phase occur? Organogenesis is the process by which the three germ tissue layers of the embryo, which are the ectoderm, endoderm, and mesoderm, develop into the internal organs of the organism. J. G. Torrey (1966), advanced the hypothesis that organogenesis in the callus tissue starts with the formation of clusters of meristematic cells (meristemoids). Organogenesis is the phase of embryonic development that starts at the end of gastrulation and continues until birth. The ectoderm gives rise to the nervous system and the epidermis, among other issues. The mesoderm gives rise to the muscle cells and connective tissue in the body. The endoderm gives rise to the gut and many internal organs. Organogenesis is helpful in regulation of cell division, cell expansion, cell and tissue type differentiation, understanding the mechanism of hormones and other plant growth regulators' action, patterning of the organ as a whole, and the study of how organs are initiated and how they develop.
