Question

Difference between oospores , basidiospores and ascospores

Answer 1

	Oospores	Ascospores	Basidiospores
1.	It is the result of union between female gametes i.e. Oogonium and male gametes i.e. Antheridium.	Ascospore is a sexual spore produced by fungi ascomycetes. It is a result of union between female gametes. I.e. Ascogonium and male gamete. i.e. Antheridium.	Basidiospore is a sexual spore produced by fungi basidiomycetes.
2.	Anthridial nuclei passes to Oogonium through fertilization tube.	Ascospores are produced inside a structure called ascus.Ascospores are produced endogenously.	Basidiospores are always produced externally on a structure called a basidium.Basidiospores are produced exogenously.
3.	They result in numerous oogonia containing one to several spherical and often brownish eggs. The oogonia are usually penetrated by one or more hyphae (antheridia) that give rise to the male nuclei.	A typical ascus bears eight ascospores.They will never be penetrated by any sort of fertilizing hypha	A typical basidium produces four basidiospores. Basidiospores are the result of an early fertilization.
