The endoderm of the gastrula turns into internal organs such as the liver and pancreas, and into the lining of some systems.
The three primary germ layers in the gastrula are the ectoderm (outer layer), mesoderm (middle layer), and endoderm (inner layer). Each layer gives rise to different tissues and organs in the developing embryo.
The stage that shows the development of the ectoderm and endoderm germ layers is the gastrula stage. During gastrulation, the single-layered blastula reorganizes into a multi-layered structure, forming the three primary germ layers: ectoderm, endoderm, and mesoderm. The ectoderm will eventually give rise to structures like the skin and nervous system, while the endoderm will form internal organs such as the gut and respiratory system.
Gastrulation is defined as a phase early in the embryonic development of most animals, during which the single-layered blastula is reorganized into a trilaminar structure known as the gastrula. These three germ layers are known as the ectoderm, mesoderm, and endoderm. These develop into the respiratory and digestive organs.
The digestive tract develops from a central cavity called the blastocoel. During embryonic development, the blastocoel is surrounded by the endoderm, which eventually forms the lining of the digestive system. This process is known as gastrulation.
After three cell layers develop, the fertilized egg is called a gastrula. During this stage, the three primary germ layers—ectoderm, mesoderm, and endoderm—form, which will eventually give rise to different tissues and organs in the developing organism. This process is part of embryonic development and is critical for proper organ formation.
endoderm, mesoderm, then ectoderm
Gastrula has cell layers that will later develop into different body structures. The three primary germ layers - ectoderm, mesoderm, and endoderm - are formed during gastrulation and give rise to various tissues and organs in the developing embryo.
The three germ layers of a gastrula are the ectoderm (outer layer), mesoderm (middle layer), and endoderm (inner layer). These layers give rise to different tissues and organs in the developing embryo through a process known as gastrulation.
The layers of the gastrula are the ectoderm, endoderm, and mesoderm. These layers give rise to different tissues and organs in the developing embryo during the process of gastrulation.
The stage when all three germ layers (ectoderm, mesoderm, and endoderm) are evident is called the gastrula stage. During gastrulation, the blastula undergoes a series of cell movements and differentiations to form the three germ layers that will give rise to all the specialized tissues and organs in the body.
The three primary germ layers in the gastrula are the ectoderm (outer layer), mesoderm (middle layer), and endoderm (inner layer). Each layer gives rise to different tissues and organs in the developing embryo.

A gastrula is an early stage in embryonic development in animals, following the blastula stage. During gastrulation, the embryo undergoes significant cell movements and rearrangements, leading to the formation of three germ layers: ectoderm, mesoderm, and endoderm. These germ layers give rise to various tissues and organs in the developing organism.
