WebAug 19, 2024 · Karyogamy is the fusion of nuclei and leads to the production of a diploid zygote. The zygote will grow, replicating the nuclei with no cytokinesis, to form the multinucleate plasmodium. A mature plasmodium (multinucleated free-flowing mass of protoplasm) can produce sclerotium (small cells) in a dry habitat. Summary
