Yes, cells do grow in the blastula stage of embryonic development. The blastula is characterized by a hollow sphere of cells, known as blastomeres, that form after several rounds of cell division following fertilization. While the overall size of the blastula does not increase significantly, the cells within it can continue to grow and differentiate as development progresses into later stages, such as gastrulation.

What happens if a small mass of cells breaks off from a human blastula?
If a small mass of cells breaks off from a human blastula, it can potentially lead to the formation of a teratoma, a type of tumor that contains tissues from all three germ layers. Teratomas have the ability to differentiate into various cell types and can grow in an uncontrolled manner. However, the exact outcome would depend on various factors such as the location and size of the mass of cells.
Is a blastula a solid ball of cells?
yes
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 cavity within the blastula called?
The central cavity within the blastula is called the blastocoel. It is filled with fluid and is surrounded by a layer of cells called the blastoderm.
Compare the frogs blastula with that of a sea star?
The frog blastula is formed through holoblastic cleavage, resulting in a multicellular blastula with a fluid-filled cavity (blastocoel). In contrast, the sea star blastula is formed through radial holoblastic cleavage, leading to a solid blastula with no blastocoel. Additionally, the frog blastula undergoes gastrulation to form a gastrula with three germ layers, while the sea star blastula directly develops into a bipinnaria larva without gastrulation.
How many cells layers are found in blastula?
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.
Which of these is a hollow ball of cells?
Blastula.
How are cells organized to form the metazoa?
blastula
The blastula is a solid ball of cells?
A blastula is an early form in the development of an embryo, consisting of a spherical layer of cells filled with fluid.

Is a blastula a solid ball of cells?
yes
An animal zygote divides to form a what?
After the zygote forms, its cells divide until they form a hollow ball of cells called a Blastula.
What is the shape of a blastula?
A blastula is typically a hollow, fluid-filled sphere formed during the early stages of embryonic development. It is characterized by a single layer of cells surrounding a central cavity called the blastocoel. The shape of a blastula is usually spherical or more irregular in some organisms.

What is the function of blastula?
The blastula is a hollow sphere of cells formed during the early stage of embryonic development. Its main function is to organize cells that will give rise to specialized tissues and organs later in development. The blastula also plays a crucial role in implantation and formation of the germ layers in the developing embryo.
