Question

Which of the following combinations of inflorescence types and their branching patterns is INCORRECT?

B VENKAT · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
 **Primary Concept**: Inflorescence types and branching patterns
 **Related Topics**: Botany, plant morphology, flowering
 **Prerequisites**: Understanding of raceme, umbel, spadix, cyme, monopodial branching, dichasial cyme, and sympodial branching.
## SOLUTION PATHWAY
**Given Information**:
Four combinations of inflorescence types and their branching patterns are given.
**Method & Steps**:
1. Analyze each option to determine if the inflorescence type matches the branching pattern.
   Reasoning: We need to understand the characteristic branching pattern associated with each inflorescence type.
2. Identify the incorrect combination.
   Working:
   * **Raceme:** A raceme is an unbranched, indeterminate inflorescence with pedicellate flowers arranged along a central axis.  It exhibits monopodial branching (main axis continues to grow).
   * **Umbel:** An umbel is an inflorescence where all the flower stalks arise from approximately the same point, giving an umbrella-like appearance. It typically shows monopodial branching, although some variations exist.
   * **Spadix:** A spadix is a fleshy spike with small flowers closely packed on a thickened axis. It is usually subtended by a large bract called a spathe.  A spadix does *not* have a dichasial cyme branching pattern.  Dichotomous branching (repeated forking into two branches) is not characteristic. Spadices tend to have flowers densely arranged on a central axis.
   * **Cyme:** A cyme is a determinate inflorescence where the terminal flower opens first, and subsequent flowers develop from lateral branches. Cymes typically exhibit sympodial branching (repeated branching from lateral buds).
3. Determine the incorrect option.
   Result: Option C (Spadix - dichasial cyme) is incorrect because spadices do not exhibit dichasial cyme branching.
   Verification: The other options are consistent with the typical branching patterns of their respective inflorescence types.
## OPTION ANALYSIS
A ✓: Raceme is correctly paired with monopodial branching.
B ✓: Umbel is typically paired with monopodial branching.
C :x: Spadix does not have a dichasial cyme branching pattern.  It has a different type of arrangement.
D ✓: Cyme is correctly paired with sympodial branching.
## LEARNING AIDS
 **Common Mistakes**:
  1. Confusing monopodial and sympodial branching:  Remembering the difference in growth patterns (main axis vs. lateral buds) is crucial.
  2. Misunderstanding the structure of different inflorescences:  A thorough understanding of the morphology of each inflorescence type is essential.
 **Quick Tips**:
  1. Draw diagrams of each inflorescence type to visualize their branching patterns.
  2. Use mnemonics or flashcards to memorize the associations between inflorescence types and branching patterns.
