Gametophyte is sexually reproducing plants which a haploid, or gamete-producing, phase of a plant. During this phase gametes are produced, which undergoes the process of fertilization to produce sporophytes.
The reproducing parts or organs of a plant are the stamen, which produces the male gametes (pollen grains) and Carpels which produces the female gametes (ovules).
The stamen is made up of the anthers and the filaments, while the carpels are made up of the style, stigma and the ovary.
Sepals and petals are specialized leaves which are parts of the flower that does not produce gametophytes.
