Verified
The process of forming three germ layers from the embryonic disk is called ________.
A) gastrulation
B) differentiation
C) fertilization
D) meiosis
E) implantation
Gastrulation
During the early stages of embryonic evolution in a wide range of animals, the simple, single-layered structure called a blastula rearranges itself into a complex, multilayered formation known as the gastrula.
Embryonic Disk
A key structure in early embryonic development, from which the embryo begins to form and differentiate into various tissues and organ systems.
Germ Layers
The three primary layers of cells (endoderm, mesoderm, and ectoderm) in an embryo from which all tissues and organs develop.

Final Answer :
A
Explanation :
Gastrulation is the process during early embryonic development where the single-layered blastula is reorganized into a multilayered structure known as the gastrula, forming the three primary germ layers: ectoderm, mesoderm, and endoderm.
