Reproduction

Asexual

- an increase in the vegetative mass or the developmentof asexual reproductive structures and spores- no union of nuclei or gametes

Anamorphic

Sexual

- involves the union of two compatible nuclei(karyogamy) followed by meiosis- involves specialized structures and spores

Teleomorphic
