During blastula there will be two germ layers 1)ectoderm 2)endoderm, after gastrulation , there will be three germ layers 1) Ectoderm 2) Endoderm 3) Mesoderm
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.
The endoderm of the gastrula turns into internal organs such as the liver and pancreas, and into the lining of some systems.
The blastula is the developmental stage that forms before the gastrula. During embryonic development, the blastula undergoes a process called gastrulation, which results in the formation of the gastrula.
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.

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.
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 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:

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.

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.
