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.

Vernadsky was most likely introduced to the term by a common acquaintance, Édouard Le Roy, during a stay in Paris. [12] Some sources claim Édouard Le Roy actually first proposed the term. [ 13 ] Vernadsky himself wrote that he was first introduced to the concept by Le Roy in his 1927 lectures at the College of France, and that Le Roy had ...
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.
The English football league system, also known as the football pyramid, is a series of interconnected leagues for men's association football clubs in England, with five teams from Wales, one from Guernsey, one from Jersey and one from the Isle of Man also competing.
A player doing a keepie-uppie Association football (more commonly known as football or soccer) was first codified in 1863 in England, although games that involved the kicking of a ball were evident considerably earlier.

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.
