AP BIOLOGY

Detailed explanation-1: -Organogenesis is defined as the development of organs, like roots, shoots, and flowers, either directly from an explant, or from the callus culture.

Detailed explanation-2: -In plant tissue culture, organogenesis is the formation of organs from the cultured explants (plant material such as roots, leaves and flowers). The organogenesis process is where the plant organs, either shoots or roots, are developed.

Detailed explanation-3: -De novo root organogenesis is the process in which adventitious roots regenerate from detached or wounded plant tissues or organs. In tissue culture, appropriate types and concentrations of plant hormones in the medium are critical for inducing adventitious roots.

Detailed explanation-4: -Organogenesis is the formation of new organs, namely, shoots.

Detailed explanation-5: -Organogenesis is the phase of embryonic development that starts at the end of gastrulation and continues until birth. During organogenesis, the three germ layers formed from gastrulation (the ectoderm, endoderm, and mesoderm) form the internal organs of the organism.
