A layer of cells and a cavity .
There is a significant change in overall size from the morula stage to the blastula stage. During the morula stage, the embryo is a solid ball of cells and is relatively small in size. However, during the blastula stage, the embryo undergoes a process called blastulation, in which the cells reorganize and form a fluid-filled cavity called the blastocoel. This results in a larger and more complex structure. The blastula stage is also characterized by the formation of two distinct cell types: the inner cell mass and the trophoblast. These cell types will give rise to the embryo and the placenta, respectively. Overall, the blastula stage represents a significant milestone in the development of the embryo.
The embryonic stage you are referring to is called the blastocyst stage. During this stage, the embryo is a hollow sphere of cells with an inner cell mass that will eventually develop into the fetus.
The blastula is a hollow sphere of cells formed during the early stage of embryonic development. Its main function is to organize cells that will give rise to specialized tissues and organs later in development. The blastula also plays a crucial role in implantation and formation of the germ layers in the developing embryo.
In mammals, the blastula forms the blastocyst in the next stage of embryonic development. Here the cells in the blastula arrange themselves in two layers: the inner cell mass and an outer layer called the trophoblast . The inner cell mass is also known as the embryoblast; this mass of cells will go on to form the embryo. At this stage of development, the inner cell mass consists of embryonic stem cells that will differentiate into the different cell types needed by the organism. The trophoblast will contribute to the placenta and nourish the embryo
the hollow ball of cells is called the Blastocyst. At which point this occurs depends on the particular species.

it is an stage in emryonic development in animals, after morula and blastula.
The 8 stages of embryo development are: fertilization, cleavage, morula formation, blastula formation, gastrulation, neurulation, organogenesis, and fetal development. Each stage involves specific changes in cell division, differentiation, and organ formation that ultimately lead to the development of a mature organism.
the blastula is an early stage of embryonic development in animals. its a hollow sphere of cells surrounding an inner fluid-filled cavity called the blastocoele formed during an early stage of embryonic development in animals
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.
An organism in the early stages of its development is an embryo.
An embryo becomes a fetus at around 9 weeks of development.
