BALASOURY · Accepted Answer

## CORE INFORMATION
✓ **Answer**: D
## CONCEPT FRAMEWORK
 **Primary Concept**: Asexual Reproduction in Sponges
 **Related Topics**: Sponge biology, asexual reproduction, budding, gemmule formation
 **Prerequisites**: Basic understanding of sponge anatomy and reproduction.
## SOLUTION PATHWAY
**Given Information**:
  The question asks about the type of asexual reproduction exhibited by gemmule formation in sponges.
  [Important conditions]: Gemmules are internal buds.
**Method & Steps**:
 1. Understand the process of gemmule formation.
  Reasoning: Sponges reproduce asexually through various methods, including budding. Gemmules are internal buds, resistant structures formed within the sponge's body.  They are released when conditions are unfavorable and can develop into new sponges when conditions improve.
  Formula/Rule: N/A
 2. Compare gemmule formation to other options.
  Working: External budding involves the formation of buds on the exterior of the parent organism. Fragmentation involves the breaking of the parent organism into fragments, each capable of forming a new individual. Binary fission involves the division of a single cell into two identical daughter cells. Internal budding, like gemmule formation, involves the formation of buds within the parent organism.
  Key Point: The key difference lies in the location of bud formation (internal vs. external).
 3. Identify the correct type of asexual reproduction.
  Result: Gemmule formation is an example of internal budding.
  Verification: The definition of gemmules aligns perfectly with the description of internal budding.
 ## OPTION ANALYSIS
A :x: External budding is incorrect because gemmules form internally.
B :x: Fragmentation is incorrect because gemmules are specifically internal buds, not fragments of the parent sponge.
C :x: Binary fission is incorrect because this is a process of cell division, not multicellular bud formation.
D ✓: Internal budding accurately describes the formation of gemmules within the sponge's body.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing internal and external budding: Pay close attention to the location of bud formation.
  2.Misunderstanding the nature of gemmules: Recognize that gemmules are specialized structures for survival and asexual reproduction.
 **Quick Tips**:
  1.Remember that gemmules are internal, resistant structures, helping to distinguish them from other forms of asexual reproduction in sponges.
  2.Associate gemmules with survival during harsh conditions and subsequent asexual reproduction.
