What are the Functions of sori on fern plant?

Sori are clusters of sporangia found on the undersides of fern fronds. Their primary function is to produce and release spores, which are essential for the fern's reproductive cycle. By facilitating asexual reproduction, sori enable the dispersal of spores into the environment, allowing ferns to colonize new areas and maintain genetic diversity. Additionally, sori protect developing spores from environmental factors until they are mature and ready for release.
