The blastula is a stage of growth of a fertilized animal egg. It has about 128 cells, and follows the formation of a blastocyst by the "morula" stage (it precedes implantation in the endometrium).

A blastula is an early form in the development of an embryo, consisting of a spherical layer of cells filled with fluid.

Both are a hollow ball of cells
After the zygote forms, its cells divide until they form a hollow ball of cells called a Blastula.
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.
Blastula only formed when the morula, a ball of cells is surrounded by a fluid-filled cavity. It is also produced by repeated cleavage of a fertilized egg.
The blastula is a single-layered ball with a fluid-filled cavity called the BLASTOCOEL in the middle (which the morula stage lacks). --Side note: The morula is a ball of cells about the same size as the original zygote and the large number of embryonic cells of the morula arrange themselves into a blastula, with the blastocoel in the middle.
human blastula and a small mass of cells breaks off
A solid ball of cells is called a morula. A morula is an embryo that is at an early stage of embryonic development.
