Aggregate fruits arise from

Options

A. single ovary of one flower
B. single ovary of many flowers
C. many ovaries of one flower
D. many ovaries of many flowers

Answer

To answer the question "Aggregate fruits arise from," we need to understand the definition and formation of aggregate fruits.

### Step-by-Step Solution:

1. **Definition of Aggregate Fruits**:
Aggregate fruits are formed from a single flower that has multiple ovaries. Each ovary develops into a small fruit, and collectively they form what is known as an aggregate fruit.

2. **Formation of Aggregate Fruits**:
In a single flower, if there are multiple carpels (the female reproductive structures), each carpel contains an ovary. When these ovaries develop, they do not fuse together; instead, they remain distinct but are grouped together to form the aggregate fruit.

3. **Identifying the Correct Option**:
- **Option 1**: Single ovary of one flower - Incorrect, as this describes a simple fruit.
- **Option 2**: Single ovary of many flowers - Incorrect, as this does not pertain to aggregate fruits.
- **Option 3**: Many ovaries of one flower - Correct, as this describes the formation of aggregate fruits.
- **Option 4**: Many ovaries of many flowers - Incorrect, as this also does not describe aggregate fruits.

4. **Conclusion**:
Therefore, the correct answer is that aggregate fruits arise from many ovaries of one flower.
