The word "auxospore" is a term used in biology to refer to a spore that is formed during the reproduction of certain algae. The IPA phonetic transcription of this word is /ɔːkˈsɒspɔː/, where the first syllable is pronounced with the same vowel sound as in "law", and the second syllable with the same vowel sound as in "not". The word is spelled using the letters "a-u-x-o-s-p-o-r-e" and is commonly used in scientific literature to describe various aspects of algal growth and reproduction.
Auxospore is a term used in biology to refer to a specialized reproductive structure that is found in certain groups of organisms, particularly diatoms. It is a non-motile, unique cell that is formed during the process of reproduction, playing a crucial role in population maintenance and continuity.
In diatoms, which are single-celled algae that are abundant in diverse aquatic environments, auxospores are formed when diatom cells reach their maximum size and undergo a process called sexual reproduction. This process allows diatoms to restore their optimal size and shape, as individual diatom cells gradually decrease in size with each subsequent division. The formation of the auxospore is an essential means for diatoms to break the cycle of cell reduction and regain their original size.
The auxospore serves as a dynamic, expanding cell that can bypass the limitations of regular cell division and undergo considerable enlargement. It plays a critical role in rejuvenating diatom populations and maintaining their overall genetic diversity. In addition to size restoration, auxospore formation also allows for the mixing of genetic material through the fusion of gametes or sexual spores, promoting genetic recombination and increasing the adaptability of diatoms to changing environmental conditions.
Overall, the auxospore is a significant reproductive structure in diatoms, ensuring their survival, genetic variability, and ecological importance in various aquatic ecosystems.
In Diatomaceae, a large cell, formed by simple growth or a conjugation, which divides to form successively smaller daughter cells, which in turn enlarge to form new auxospores.

The word auxospore derives from the combination of two Latin roots: auxo, meaning to increase or to grow, and spora, meaning seed or spore.
