In fungi vegetative, asexual, and sexual all three types of reproduction take place. The sexual reproduction takes place with the help of some spores like oospores, ascospores and basidiospores. Their sexual cycle is conducted mainly in three steps - $\left(\mathrm{a.}\right)$ Plasmogamay: Fusion of protoplasms between two motile or non-motile gametes $\left(\mathrm{b.}\right)$ Karyogamy: Fusion of two nuclei $\left(\mathrm{c.}\right)$ Meiosis: Zygote undergoes meiosis and forms haploid spores.
