A nonmotile female gamete formed in the oogonium of some algae, fungi, oomycetes, or bryophytes is an oosphere. [2] When fertilized, the oosphere becomes the oospore. [clarification needed] When egg and sperm fuse during fertilisation, a diploid cell (the zygote) is formed, which rapidly grows into a new organism.

An oospore is a thick-walled sexual spore that develops from a fertilized oosphere in some algae, fungi, and oomycetes. [1] They are believed to have evolved either through the fusion of two species or the chemically induced stimulation of mycelia , leading to oospore formation.
The antheridia will then form fertilization tubes connecting the antheridial cytoplasm with each oosphere within the oogonia. A haploid nucleus (gamete) from the antheridium will then be transferred through the fertilization tube into the oosphere, and fuse with the oosphere's haploid nucleus forming a diploid oospore.
