The Hibiscus rosa-sinensis, like all angiosperms is sporophyte dominant, meaning that the multicellular diploid is the most prevalent. The life cycle for the Hibiscus rosa- sinensis follows the alternation of generations. Which means the sporophyte undergoes meiosis to produce haploid cells. The haploid cell then develops into a multicellular haploid, which is called the gametophyte. The gametophyte then undergoes mitosis to produce gametes. One of the gametes is then fertilized and forms a zygote. The zygote undergoes mitosis to produce what we see as the flower or the sporophyte portion of the plant.

 The Hibiscus rosa- sinensis is a bisexual plant, meaning that the plant contains both male and female reproductive anatomy. The male reproductive structure is referred to as the stamen and the female reproductive structure is referred to as the ovary. If a part of the stamen is removed as well as the petals of the flower, the flower cannot take part in any form of genetic crosses with other species of the Hibiscus rosa- sinensis. The pollen on the Hibiscus rosa- sinensis has a high fertility rate of over 60%. The stalks of the Hibiscus rosa- sinensis only contain one flower. The Hibiscus rosa-sinensis is also  heterosporous, meaning that the plant contains microspores and megaspores that are produced via meiosis. The microspores make male gametophytes and the megaspores make female gametophytes.


The Hibiscus rosa-sinensis is an angiosperm meaning that it has a seed covering. The seed covering on this plant tends to be dry and hard. When the plant produces fruit it tends to be in an oval shape. The flowers tend to be 4 to 8 inches and the plant flowers    year around when it is in the right habitat.

The Hibiscus rosa-sinensis requires frequent watering and a lot of fertilizer when it is first planted. The Hibiscus rosa- sinensis also requires full to partial sun.
