Fruit needs a lot of water to develop and if there is not adequate rainfall, fruit may fail to grow if not irrigated. When a grain of pollen reaches the stigma, it creates a pollen tube for the sperm to journey down the style and fertilize the ovule; fertilized ovules become seeds. By manipulating pollination, scientists and gardeners have created many new varieties of fruits, and many types that are resistant to various diseases. Fertilization is the death of the flower, as the petals drop or wither at this point and the ovary starts to enlarge and ripen into what we know as fruit.
