Explanation:
Anthers release pollen, which lands on the stigma of another flower of the same species. The pollen grain produces a pollen tube that grows down the style, to the ovary, and into the ovule. The sperm cell fertilizes the egg cell. The ovule develops into the seed, and the ovary becomes the fruit.
<em>During fertilization in plants, the anther which carries pollen releases pollen grains. Once the pollen lands on the stigma of a flower of the same species, it germinates. The pollen grain produces a pollen tube that grows through the style of the stigma down to the ovary and into the ovule. One of the sperm cells fuses with the egg cell of the ovule to form the zygote while the other sperm cell fuses with the polar nuclei to form the endosperm in a process known as double fertilization. After fertilization, the fertilized ovule becomes the seed and the ovary becomes the fruit. </em>
