Fungi are immobile and lack capacity for locomotion, Rice University states. They form reproductive spores which help them reproduce. The spores can be moved by wind or rain from one place to another. Fungi can multiply both sexually and asexually, according to MicrobiologyBytes. Asexual methods of fungal growth include binary fission, fragmentation and sporulation.
With bud formation or binary fission, such as in yeasts, two cells form from a single one. The process starts with cellular events characterized by the development of a ring of chitin around the region where bud synthesis begins, MicrobiologyBytes mentions. A nuclear event of mitosis commences, leading to growth of a new cell wall. Asexual spores develop during the mitosporic or anamorphic phase of the fungal life cycle. Each species of fungus can undergo a mitosporic phase more than once. In some cases, the mitosporic states of different fungi species seem identical. The sexual propagation phase of most fungi affords an opportunity for variety. The reproduction entails two haploid nuclei (n+n) or a diploid (2n) nucleus of mating type. If two haploid forms are involved initially, they must combine to make up a diploid. After fusion, the nuclei undergoes meiosis, a process that introduces variation. Eventually, spores that can stand harsh conditions are formed.
