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 term noosphere was first used in the publications of Pierre Teilhard de Chardin in 1922 [10] in his Cosmogenesis. [11] 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]
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.
Microsoft Office for Windows [132] started in October 1990 as a bundle of three applications designed for Microsoft Windows 3.0: Microsoft Word for Windows 1.1, Microsoft Excel for Windows 2.0, and Microsoft PowerPoint for Windows 2.0. [133] Microsoft Office for Windows 1.5 updated the suite with Microsoft Excel 3.0. [134]
[97] [98] Versions of PowerPoint Mobile for Windows Phone 7 can also watch presentation broadcasts streamed from the Internet. [99] In 2015, Microsoft released PowerPoint Mobile for Windows 10 as a universal app. In this version of PowerPoint users can create and edit new presentations, present, and share their PowerPoint documents.

Microsoft Word is a word processing program developed by Microsoft.It was first released on October 25, 1983, [13] under the name Multi-Tool Word for Xenix systems. [14] [15] [16] Subsequent versions were later written for several other platforms including: IBM PCs running DOS (1983), Apple Macintosh running the Classic Mac OS (1985), AT&T UNIX PC (1985), Atari ST (1988), OS/2 (1989 ...
