Web12 okt. 2024 · Do zygotes go through mitosis? Zygotes divide through a process known as mitosis, in which each cell doubles (one cell becomes two, two becomes four, and so on). When these two haploid cells join, they form a single diploid cell that contains all necessary chromosomes. The zygote then travels down the fallopian tube to the uterus. 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.
