Question

What type of inflorescence is characterized by a flattened main axis and sessile flowers?

Mr. NARESH KUMAR K · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
 **Primary Concept**: Inflorescence types
 **Related Topics**: Botany, plant morphology, flower arrangement
 **Prerequisites**: Basic understanding of floral structures and terminology.
## SOLUTION PATHWAY
**Given Information**:
  The inflorescence has a flattened main axis and sessile flowers (flowers without stalks).
  [Important conditions]: We need to identify the inflorescence type based on these characteristics.
**Method & Steps**:
 1. Analyze the given characteristics: flattened main axis and sessile flowers.
  Reasoning:  Different inflorescence types have distinct arrangements of flowers on the main axis.
  Formula/Rule: There's no formula, but a knowledge-based approach is needed.
 2. Consider the options:
  Working: 
            * **Spike:**  Flowers are sessile (without stalks) along an elongated axis, but the axis is not necessarily flattened.
            * **Raceme:** Flowers are stalked (pedicellate) along an elongated axis.
            * **Capitulum (Head):** Flowers are sessile on a flattened, expanded receptacle (the main axis).
            * **Umbel:** Flowers appear to arise from a single point, with stalks of equal length.
  Key Point: The key here is the combination of a flattened main axis and sessile flowers.
 3. Identify the matching inflorescence type:
  Result: Capitulum is the only inflorescence type that matches both characteristics.
  Verification: Review the definitions of each inflorescence type to ensure the choice is accurate.
 ## OPTION ANALYSIS
A :x: Spike inflorescences have sessile flowers, but the axis is not flattened.
B :x: Racemes have stalked, not sessile, flowers.
C ✓: Capitulum inflorescences have a flattened receptacle (main axis) with sessile flowers, perfectly matching the description.
D :x: Umbels have flowers arising from a single point with stalks of equal length, neither matching the description.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing capitulum with spike: Remembering that capitulum has a flattened receptacle is key.
  2.Overlooking the 'sessile' characteristic:  Focusing only on the flattened axis can lead to incorrect choices.
 **Quick Tips**:
  1.Make flashcards with diagrams of different inflorescence types.
  2.Use mnemonics to remember the key features of each type (e.g., Capitulum - 'cap' like a flattened head).
