Answer 2

Oospores are produced when male gametes (reproductive nuclei) enter a large spherical cell (oogonium) and fertilize the eggs within. The oogonia are usually penetrated by one or more hyphae (antheridia) that give rise to the male nuclei.

Zygospores do not occur inside any kind of enclosing structure, but are produced by the direct fusion of two hyphal protrusions (suspensors) from neighbouring filaments. Usually, zygospores are recognized as large, nearly spherical, often dark brown or black, rough-walled spores with two connecting hyphae, representing the two mating gametangia.

Ascospores are produced within spherical to cylindrical cells called as asci, most often in groups of four or eight. Usually, the asci are produced within some kind of enclosing structure and thus, are not found exposed on the hyphae.

Basidiospores are always produced externally on a structure, called as a basidium. Basidia come in a variety of forms, but those commonly encountered on moulds will be club-shaped and bear four or eight spores on sharp projections at the apex.
