From inner to outer, the germ cell layers are the endoderm, mesoderm, and ectoderm.
Each of the three layers develops into a different part of the embryo: the endoderm into the respiratory, auditory, and digestive system; the mesoderm into the skeleton and muscles; and the ectoderm into the skin, tooth enamel, and nervous system.

What is the stage all three germ layers of tissue are evident?
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.
Which of these has cell layers that will later develop into different body structures?
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.
What is the opening outside of the gastrula called?
The opening outside of the gastrula is called the blastopore. It is the initial opening that forms during gastrulation, where cells migrate to form the three germ layers.
What is gastrula?
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.
What is the relationship between gastrula and blastula?
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:
What are the layers in the gastrula?
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.

Contrast the structure of a blastula with that of a gastrula?
Blastula is a hollow structure, that consists of a single layer of morphologically distinct cells, trophoblasts, forming the periphery of sphere. The space enclosed within trophoblast layer is filled with a fluid called as blastoceol. At one end of blastula, there is a cluster of undifferentiated cells, known as inner cell mass. During the gastrula stage the inner cell mass began to align in a plane (like a disk) giving rise to three distinct germ layers from which the future organs will develop.
Which organ systems develop from each of the three layers in gastrula?
reproductive
What is the three layers formed during gastrula stage?
the phineas and ferb ejaculation
Does porifera have 3 germ layers?
No they do not. I am not certain as to whether they have 0 or 2 germ layers but it is one of the two.
What marks the beginning of germ layer development in ambryo?
Germ layer development in embryos begins with gastrulation, the process by which a blastula reorganizes into a gastrula with distinct germ layers (ectoderm, mesoderm, and endoderm). During gastrulation, cells migrate and differentiate to form these primary germ layers, setting the foundation for future tissue and organ development.
How many germ layers do pigs have?
Three cell layers known as the ectoderm, mesoderm, and endoderm. They are also referred to as the primary germ layers, because all of the organs and tissues of the embryo will be formed from them.
