Question

body cavity is formed by replacing blastocoel in​

Answer 1

Answer:

Body cavity is formed by replacing blastocoel in​ phylum Aschelminthes.​

Explanation:

• In roundworms, the area between the body wall and the digestive tube is called a pseudocoelom.
• Instead of a secondary cavity within the embryonic mesoderm, the pseudocoelom arises from the embryo's blastocoel (which leads to a real body cavity or coelom).
• The principal bodily cavity that houses and surrounds the digestive system and other organs in the majority of mammals is known as the coelom.
• A coelom can function as a hydrostatic skeleton or as a shock absorber. Internal organs may stretch and move independently of the outside body wall due to the cavity.
• The liquid that fills the coelom is known as coelomic fluid.
• Pseudocoelom refers to the fictitious body cavity that lies between the endoderm of the gut and the mesoderm of the body wall.

Answer 2

The body cavity is formed by replacing blastocoel in​ roundworms.

Roundworms:

• Roundworms are the popular name for Aschelminthes.
• They are distinguished by having a pseudocoelom.
• It is now an extinct phylum of invertebrates, and the creatures it once included are now organized into 10 other phyla.
• The body is triploblastic and bilaterally symmetric.
• The body is long, slender, and not segmented; it tapers out at the end.
• There is no evidence of metameric segmentation.
• Males are often smaller than females since they are dioecious.
• Bilaterally symmetrical, triploblastic, and dioecious creatures are aschelminthes.
• They could be terrestrial, aquatic, free-living, or parasitic on both plants and animals.

Where does the blastocoel form?

• The blastocoel is replaced by the archenteron during mid-gastrulation during the subsequent stage of embryonic development, amphibian gastrulation.
• The blastocoel has been destroyed at the end of gastrulation.
