A layer of cells and a cavity .
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.
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

A blastocyte is an undifferentiated cell in the blastula stage of an embryo.
In mammals, the blastula forms the blastocyst in the next stage of embryonic development.

it is an stage in emryonic development in animals, after morula and blastula.
Blastula
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
embryo
An organism in the early stages of its development is an embryo.
An embryo is a multicellullar, eukaryotic organism in an early stage of development.
A blastocyst is a distinctive stage of a mamalian embryo. It is a form of Blastula that develops from a berry like cluster of cells, the morula. It continues to form and grow from there.
