The embryonic stage in which cell migration and differentiation occurs is known as gastrulation. During this process, cells undergo extensive reorganization to form the three germ layers - ectoderm, mesoderm, and endoderm, which give rise to various tissues and organs in the developing embryo.
The process of embryonic tissue development where tissue layers form during animal development is called gastrulation. This process involves the rearrangement and differentiation of cells to create distinct layers that will give rise to different body structures and organs.
Germ layers.
Embryonic layers are the three primary layers of cells in the early embryo that give rise to all the tissues and organs in the body. These layers are the ectoderm (outer layer), mesoderm (middle layer), and endoderm (inner layer). During development, these layers differentiate and specialize to form various structures in the body.
About 17 days after fertilization, embryonic stem cells begin to develop into more specialized cells. At this stage, the embryo forms a structure called the gastrula, which leads to the differentiation of three germ layers: ectoderm, mesoderm, and endoderm. These germ layers give rise to various cell types and tissues in the developing organism.

Differentiation in embryonic development typically begins in the gastrulation stage. During gastrulation, the three germ layers (ectoderm, mesoderm, endoderm) form, and cells start to differentiate into specific cell types, laying the foundation for the development of various tissues and organs in the embryo.
Germ layers.
There are three layers of embryonic tissue present in the pig. These layers are called the ectoderm, mesoderm and the endoderm.
The blastula is an embryonic structure that is formed from one cell layer. This later forms the three cell layered gastrula. All of the layers of the organism are formed from these three layers. See the link below:

During embryonic development, cells specialize to form different types of tissues and organs in the body through a process called differentiation. This specialization allows cells to take on specific functions and roles, contributing to the overall structure and function of the organism. Differentiation is critical for the growth and development of a healthy, functioning organism.
The first major event in organogenesis is the formation of the three primary germ layers: ectoderm, mesoderm, and endoderm, which occurs during the gastrulation phase of embryonic development. These layers give rise to all the organs and tissues in the body. Following gastrulation, organogenesis progresses through the differentiation and morphogenesis of structures from these germ layers. This complex process ultimately leads to the development of functional organs and systems.
Sponges have two germ layers therefore they are diploblastic.
