What is the only fruit that does not have seeds?

The only fruit that does not have seeds is the banana. Technically, bananas do have seeds, but they are so small and undeveloped that they are not noticeable and are practically infertile. Bananas reproduce asexually through a process called parthenocarpy, where the fruit develops without the need for pollination. This is why bananas that we buy at the supermarket have no seeds – they are the result of cultivated, seedless varieties. However, wild bananas still have seeds and are much less common.
