embryogenesis
Early developmental unfolding
Embryogenesis is the process by which an embryo forms and develops.
In animals, it begins with fertilization and continues through the early stages of cell division and differentiation until basic body structures emerge.
In plants, embryogenesis occurs within the seed.
The term appears primarily in scientific and medical contexts: The researchers studied embryogenesis in zebrafish.
