STERIGMATA Meaning and
Definition
-
Sterigmata is a term commonly used in the field of mycology, the scientific study of fungi, to refer to the short, slender projections that emerge from the surface of a basidium. A basidium is a reproductive structure found in certain types of fungi, such as mushrooms and bracket fungi.
These sterigmata act as attachment points for the spores, which are the reproductive cells of fungi. Typically, multiple sterigmata are present on each basidium, and they are responsible for holding the spores until they are mature and ready for dispersal. As the spores mature, they become detached from the sterigmata and are released into the surrounding environment. This mechanism allows fungi to effectively disperse their spores over a wide area, ensuring their reproductive success.
The number and arrangement of sterigmata on a basidium can vary depending on the fungal species. Some fungi may have just a few sterigmata, while others may have many, arranged in different patterns. The shape and size of the sterigmata can also differ between species.
The study of sterigmata is crucial in understanding the reproductive biology and taxonomy of fungi. By examining the number, arrangement, and features of sterigmata, mycologists can identify and classify different fungal species, contributing to the overall knowledge and understanding of fungi and their ecological roles.
Etymology of STERIGMATA
The word "sterigmata" comes from the Greek word "stereos" meaning "soli" or "firm", and "gizein" meaning "to fasten" or "to fix". In biology, "sterigmata" refers to the small, sterile cells that are present on the surface of basidia (the reproductive structures in fungi) from which the basidiospores are produced.
