In plants, the zygote may be polyploid if fertilization occurs between meiotically unreduced gametes. In land plants, the zygote is formed within a chamber called the archegonium. In seedless plants, the archegonium is usually flask-shaped, with a long hollow neck through which the sperm cell enters. As the zygote divides and grows, it does so inside the archegonium. WebFertilization is the fusion of an egg and a sperm, both produced through meiosis. F. forms the zygote which then grows through mitosis. Once the new grown organisms need its own germ cells meiosis start again.
