How does the morula stage of sea star development differ from the blastula stage?
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.

What is gastrulla?
it is an stage in emryonic development in animals, after morula and blastula.
What comes first gastrula or blastula?
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.
Is there a significant change in overall size from morula to blastula stage.?
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.
What happens during the morula stage of human development?
During the morula stage of human development, the zygote undergoes several rounds of cell division to form a solid ball of cells. At this stage, the cells are still undifferentiated and are tightly packed together. The morula will eventually develop into a blastocyst, which is necessary for successful implantation into the uterus.
A blastula is a stage in the development of an embryo that consists of a?
hollow ball of cells formed after the morula stage. It is characterized by a fluid-filled cavity called the blastocoel surrounded by a layer of cells called the blastoderm. The blastula is an early stage in embryonic development before gastrulation occurs.
Is morula the first stage of development?
Yes, the morula is the stage of development after the zygote undergoes multiple rounds of cell division and forms a solid ball of cells. It is the early stage of embryonic development before it develops into a blastocyst.
Where does blastocysts come from?
Blastocyst stage follows the morula stage of embryo development.
Whats the difference between morula and blastula?
An egg undergoes cell division and starts to become an embryo after fertilization. One cell divides into two, these then cleave into four, those four cells become eight, and so on. When there are a hundred or more cells, the embryo becomes a solid mass of cells called a morula. In most species the mass next transforms into a hollow sphere called a blastula.
What are the 8 stages of embryo development?
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.
What is a solid ball of cells?
A solid ball of cells is called a morula. A morula is an embryo that is at an early stage of embryonic development.
What stage occurs between the 4 cell stage and 16 cell stage in embryonic development?
The stage that occurs between the 4-cell stage and the 16-cell stage in embryonic development is the morula stage. The morula is a solid ball of cells formed by multiple divisions of the fertilized egg.
What is the composition of a 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
