Question

Answer

Answer

Fluid filled cavity present within blastula is called blastocoel

Answer

A blastula is a sphere of cells surrounding a blastocoel. The blastocoel is a fluid filled cavity which contains amino acids, proteins, growth factors, sugars, ions, and other components which are necessary for cellular diffrentation. The blastocoel also allows blastomers to move during the process of gastrulation. Blastocoel is formed during an early stage of embryonic development in animals.

Answer

Coel means cavity and blasto is related to blastula

Answer

A single-celled zygote will undergo multiple rounds of cleavage, or cell division, in order to produced a ball of cells, called a blastula, with a fluid-filled cavity in its center, called a blastocoel.

Answer

D

Answer

Blastocoel in Blastula

The correct answer is option 'D', blastocoel. The blastula is an early embryonic stage in animal development that follows the morula stage. During this stage, the blastula is a hollow ball of cells with a fluid-filled cavity called the blastocoel.

1. Blastula Formation:
- After the formation of the morula, the cells undergo a process called blastulation, which leads to the formation of a blastula.
- Blastula formation involves the rearrangement and differentiation of cells to form a hollow sphere.
- The blastula is formed from a single layer of cells called blastomeres.

2. Blastocoel:
- The blastocoel is the fluid-filled cavity within the blastula.
- It is formed as a result of the rearrangement of blastomeres during blastulation.
- The blastocoel is surrounded by a single layer of cells known as the blastoderm.

3. Functions of Blastocoel:
- The blastocoel provides a space for the development and movement of cells during embryogenesis.
- It also plays a crucial role in the establishment of the embryonic germ layers.
- The blastocoel allows for the formation of the blastopore, which eventually gives rise to the archenteron and the digestive cavity.

4. Importance of Blastula Stage:
- The blastula stage is a critical step in animal development as it marks the transition from a solid ball of cells (morula) to a hollow ball of cells (blastula).
- It sets the stage for the next developmental processes, such as gastrulation and organogenesis.

In summary, the fluid-filled cavity present within the blastula is called the blastocoel. The blastocoel plays a vital role in providing space for cell movement and the establishment of germ layers during embryogenesis.
