Aggregate fruit formed from

B VENKAT · Accepted Answer

## CORE INFORMATION
✓ **Answer**: A
## CONCEPT FRAMEWORK
**Primary Concept**: Fruit Development and Ovary Types
**Related Topics**: Flower structure, carpel, fruit classification
**Prerequisites**: Knowledge of plant reproductive structures, particularly the ovary and its components.
## SOLUTION PATHWAY
**Given Information**:
* The question asks about the origin of aggregate fruit.
* Options involve different ovary types: multicarpellary vs. monocarpellary, apocarpous vs. syncarpous.
**Method & Steps**:
1. **Define Aggregate Fruit**: Aggregate fruits develop from a single flower with multiple separate pistils (each containing an ovary).
  Reasoning: This defines the key characteristic of an aggregate fruit.
2. **Define Apocarpous Ovary**: An apocarpous ovary is one where multiple carpels are free from each other (not fused).
    Reasoning: This connects the structure to the fruit type.
3. **Define Syncarpous Ovary**: A syncarpous ovary is one where multiple carpels are fused together.
    Reasoning: This contrasts with apocarpous and helps eliminate options.
4. **Relate Ovary Type to Aggregate Fruit**: Since aggregate fruits develop from multiple separate pistils, they must originate from a multicarpellary apocarpous ovary.
    Reasoning:  This links the structure to the development.
5. **Eliminate Options**: Options B and D are incorrect because they describe syncarpous ovaries. Option C is incorrect because it describes a monocarpellary ovary.
    Reasoning: This systematically eliminates incorrect choices.
## OPTION ANALYSIS
[A] ✓: Multicarpellary apocarpous ovaries consist of multiple separate carpels. Each carpel develops into a small fruitlet, and the collection of these fruitlets forms an aggregate fruit.
[B] :x: Multicarpellary syncarpous ovaries have fused carpels and develop into a single fruit, not an aggregate fruit.
[C] :x: Monocarpellary ovaries have only one carpel and develop into a simple fruit, not an aggregate fruit.
[D] :x: Monocarpellary syncarpous ovaries have only one carpel and develop into a simple fruit, not an aggregate fruit.
## LEARNING AIDS
**Common Mistakes**:
1. **Confusing Aggregate and Multiple Fruits**: Aggregate fruits come from a single flower, while multiple fruits come from an inflorescence.
    How to avoid: Focus on the origin - single flower vs. multiple flowers.
2. **Misunderstanding Carpellary terms**: Not differentiating between apocarpous and syncarpous ovaries.
    How to avoid: Remember 'apo' means separate, and 'syn' means together.
**Quick Tips**:
1. Visualize: Imagine a strawberry (aggregate fruit) - it has many separate parts coming from different carpels.
2. Mnemonics: 'A'ggregate comes from 'A'pocarpous.
