Oospore vs. Oosphere — What's the Difference?

A thick-walled zygote developed from a fertilized oosphere, especially in an oomycete.

(botany) A large nonmotile egg cell formed in an oogonium and ready for fertilization

An oospore is a thick-walled sexual spore that develops from a fertilized oosphere in some algae, fungi, and oomycetes. They are believed to have evolved either through the fusion of two species or the chemically-induced stimulation of mycelia, leading to oospore formation.In Oomycetes, oospores can also result from asexual reproduction, by apomixis.

A nonmotile female gamete formed in the oogonium of an alga, fungus, oomycete, or bryophyte.

(biology) A fertilized female zygote, having thick chitinous walls, that develops from a fertilized oosphere in some algae and fungi

An unfertilized, rounded mass of protoplasm, produced in an oögonium.

A special kind of spore resulting from the fertilization of an oösphere by antherozoids.

An analogous mass of protoplasm in the ovule of a flowering plant; an embryonic vesicle.

A thick-walled sexual spore that develops from a fertilized oosphere in some algae and fungi

Used especially of lower plants
