Pineapple fruit develops from

Options

A. unilocular polycarpellary flower
B. multipistillate syncarpous flower
C. multilocular monocarpellary flower
D. a cluster of compactly born flowers on an axis

Answer

**Step-by-Step Solution:**

1. **Identify the Type of Flower**: Pineapple fruit develops from a specific type of flower structure. It is important to note that pineapple is not a simple fruit but a multiple fruit formed from multiple flowers.

2. **Understand the Flower Structure**: The pineapple fruit develops from a cluster of flowers that are compactly borne on a common axis. This means that instead of developing from a single flower, it develops from many flowers that are closely packed together.

3. **Number of Flowers Involved**: Pineapple can produce up to 200 flowers that contribute to the formation of the fruit. Each of these flowers plays a role in the development of the final fruit structure.

4. **Formation of the Fruit**: As the flowers develop, their ovaries transform into berries. This process results in the formation of a large, compact multiple accessory fruit, which is characteristic of pineapples.

5. **Arrangement of the Fruit**: The fruit of the pineapple is arranged in a unique pattern, with interlocking helices. Specifically, there are 8 helices in one direction and 13 in the opposite direction, contributing to the distinctive appearance of the pineapple.

6. **Conclusion**: Based on the above information, we conclude that the pineapple fruit develops from a cluster of compactly borne flowers on the axis.

**Final Answer**: Pineapple fruit develops from a cluster of compactly borne flowers on the axis.
