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.
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.
The correct order of developmental sequence is: Fertilization -> Zygote -> Cleavage -> Blastula -> Gastrula -> Embryo -> Meiosis -> Adult.
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.
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.
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.
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.
it is an stage in emryonic development in animals, after morula and blastula.
yes
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.

A Blastula is the usually spherical structure produced by cleavage of a zygote, consisting of a single layer of cells (blastoderm) surrounding a fluid-filled cavity (blastocoele). It is the early form of an animal embryo that develops from a morula. It is also called a blastosphere.
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.
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 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).
