After he formation of morula(in cleavage),a number of changes occur which lead to blastulation.A cavity appears due to compact rearrangement of of cells in embryo within the upper half,now called blasocoel.The embryo now called blastula.The cells now move to new positions according to function they have to perform.
What else can I help you with?
What is blastulation explain briefly?
Blastulation is the process of the cleavage subdividing the mass of the zygote until a cluster of cells known as blastula are formed
Is blastulation and gastrulation one and the same thing?
No, blastulation and gastrulation are distinct processes in embryonic development. Blastulation is the formation of the blastula from the zygote, while gastrulation is the process during which the three germ layers (ectoderm, mesoderm, and endoderm) are formed from the blastula.
What is produced by the end of blastulation?

Is blastulation and gastrulation one and same thing?
Blastulation is when the cells move to form a hollow "ball". Gastrulation is when it bends upon itself to make 3 layers, called the endoderm, the mesoderm, and the ectoderm.
What is metamorphôsis?
Metamorphosis is the change of form such as that occurs when a tadpole changes into a frog.
What is the steps of a frog being born?
The frog is in an egg, then the egg hatches to form a tadpole. The tadpole grows back legs, then front flippers. Finally, metamorphosis occurs, and voila! Adult frog.
What are the satges of growth and development?
the stages of growth are: gametogenesis fertilization cleavage or segmentation blastulation gastrulation organogenesis
When does the cleavage reaction occur?
The cleavage reaction typically occurs during the later stages of embryonic development, specifically during the process of blastulation. This reaction involves the division of the zygote into smaller, specialized cells called blastomeres, setting the stage for the formation of a multicellular organism.
What is Hoof Rot?
Bacterial infection of the hoof, which primarily occurs in the frog of the hoof, not the actual hoof.
How does the amount of yolk affect blastulation?
The amount of yolk present in an egg can affect blastulation by influencing the cleavage pattern and rate of cell division. Eggs with more yolk tend to have slower and asynchronous cleavage, which can impact the formation of the blastula. Higher yolk content may also affect the size and nutrition available to the developing embryo during blastulation.
Fertilized egg enters cell division without further growth in volume?
This process is called cleavage. Cleavage is a series of rapid cell divisions without cell growth that occurs immediately after fertilization to form a multicellular embryo. Each division results in smaller and smaller cells called blastomeres.
Why is the bottom of your horses hoof black around the frog?
A black substance around the frog is often thrush. Thrush is a disease that usually occurs because the horse is living in filth or a dirty stall for long periods.
