प्रश्न
How does Plasmodium reproduce. Is this method sexual or asexual?
उत्तर
Plasmodium reproduces by a process known as multiple fission. Multiple fission is a type of asexual reproduction in which a single parent cell divides into several daughter individuals. In this process, the parent nucleus divides several times into a number of daughter nuclei. Later the cytoplasm divides into as many pieces as the the number of nuclei and each piece surrounds each nucleus. Each uninucleate piece develops an outer membrane and finally the parent cell divides into several uninucleate individuals.
