Question

If karyogamy is followed by meiosis and spores are produced exogenously, which fungal group is likely being described?

Mr. NARESH KUMAR K · Accepted Answer

## CORE INFORMATION
✓ **Answer**: D. Basidiomycetes
## CONCEPT FRAMEWORK
 **Primary Concept**: Fungal life cycle and classification
 **Related Topics**: Karyogamy, meiosis, spore formation, fungal reproduction
 **Prerequisites**: Basic knowledge of fungal biology and the reproductive strategies of different fungal groups.
## SOLUTION PATHWAY
**Given Information**:
The question describes a specific sequence of events in fungal reproduction: karyogamy followed by meiosis and exogenous spore production.
**Method & Steps**:
1. Analyze the given reproductive sequence.
  Reasoning: Karyogamy (nuclear fusion) followed by meiosis (reductional division) is a common pattern in sexual reproduction of fungi.
  Formula/Rule: N/A
2. Identify the fungal group known for exogenous spore production after this sequence.
  Working: Basidiomycetes are the only group among the choices that fits this description, producing spores exogenously on basidia after karyogamy and meiosis.
  Key Point:  The exogenous nature of spore formation is the key differentiating factor.
3. Select the correct answer.
  Result: Basidiomycetes
  Verification: The reproductive pattern described is consistent with the life cycle of Basidiomycetes.
 ## OPTION ANALYSIS
A :x: Ascomycetes produce spores endogenously.
B :x: Zygomycetes produce spores endogenously.
C :x: Chytridiomycetes have diverse reproductive strategies, but not typically this specific combination.
D ✓: Basidiomycetes are characterized by exogenous spore production after karyogamy and meiosis.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing endogenous and exogenous spore production in fungi.
  2.Overlooking the importance of the sequence of karyogamy and meiosis.
 **Quick Tips**:
  1.Create flashcards with fungal groups and their characteristic reproductive features.
  2.Draw diagrams of the life cycles of different fungal groups.
