eimsori [14]

Shortly after gastrulation, the body and organs of the embryo begin to form. This process is called <u>embryogenesis.</u>

<u></u>

  • The process by which an embryo transforms into a fetus is known as embryogenesis.
  • The three germ layers that eventually give rise to the various organs in the animal body are formed as a result of gastrulation.
  • Embryogenesis is the name of this process. As a result of differentiation, organs emerge from the germ layers.
  • The process of creating and growing an embryo from a zygote (zygotic embryogenesis) or a somatic cell is known as embryogenesis (somatic embryogenesis).
  • An incredibly well-organized series of cell division, expansion, and differentiation takes place during embryo development.
