Question

The archenteron in a developing gastrula will eventually give rise to which structure in the adult organism?

Mr. NARESH KUMAR K · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
 **Primary Concept**: Gastrulation and Embryonic Development
 **Related Topics**: Germ layers, Digestive system development, Archenteron formation
 **Prerequisites**: Understanding of the process of gastrulation and the formation of the three germ layers (ectoderm, mesoderm, endoderm).
## SOLUTION PATHWAY
**Given Information**:
  The question asks about the fate of the archenteron during gastrulation.
  The archenteron is the primitive gut formed during gastrulation.
**Method & Steps**:
 1. Understand Gastrulation:
  Reasoning: Gastrulation is a crucial stage in embryonic development where the single-layered blastula reorganizes into a multi-layered gastrula.  This involves the invagination of cells to form the archenteron.
  Formula/Rule: N/A
 2. Identify the Archenteron's Fate:
  Working: The archenteron is the precursor to the digestive tract.  The endoderm, the innermost germ layer, lines the archenteron and will eventually form the lining of the digestive system, including the stomach, intestines, and associated organs.
  Key Point: The archenteron is not directly involved in the formation of the neural tube, notochord, or coelom (body cavity), although these structures develop in close proximity to it during gastrulation.
 3. Final Conclusion:
  Result: The archenteron develops into the digestive tract of the adult organism.
  Verification: This is a fundamental concept in developmental biology.  Textbooks and reliable online resources confirm this.
 ## OPTION ANALYSIS
A :x: The neural tube develops from the ectoderm.
B :x: The notochord develops from the mesoderm.
C ✓: The digestive tract develops from the endoderm lining the archenteron.
D :x: The coelom develops from the mesoderm.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing the archenteron with the blastocoel (the fluid-filled cavity of the blastula):  The blastocoel is largely displaced during gastrulation.  The archenteron is a newly formed cavity.
  2. Incorrectly associating the archenteron with other germ layer derivatives: Remember the endoderm's role in gut development.
 **Quick Tips**:
  1.Visualize the process of gastrulation: Diagrams and animations are helpful in understanding the formation and fate of the archenteron.
  2.Mnemonic:  Endoderm = Endo (inside) + derm (skin/layer) –  lining of the digestive tract.
