Sporulation is a type of asexual reproduction which occurs in organisms such as fungi, bacteria. In sporulation, specialized cells transformed into a hard resistant resting structure to overcome unfavourable condition. On the return of favourable conditions spores germinate to form new offspring. Sporulation is very common in fungi.
