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 happens during the morula stage of human development?
Blastula
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 form divides many times to form a blastula?
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).
What is the hollow ball stage of cleavage?
The developmental stage in which the embryonic cells form a hollow sphere (actually its full of fluid) is called a blastula.
Where does blastocysts come from?
Blastocyst stage follows the morula stage of embryo development.
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.
A blastula is a stage in the development of an embryo that consists of a?
A layer of cells and a cavity .
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
How do the cells in a blastocyst as it becomes an embryo?
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.
What is a bastocyst?
Believe you meant "blastocyst". Defined as a distinctive stage of a mammalian embryo. It is a form of blastula that develops from a berry-like cluster of cells, the morula. A cavity appears in the morula between the cells of the inner cell mass and the enveloping layer. This cavity becomes filled with fluid. The blastocyst differs from the blastula in that it is composed of two already differentiated cell types, the inner cell mass and the enveloping layer.
What is the function of blastula?
it does not have a function it is just an intermediate embryonic stage
