What is another word for secondary prothallium?
Pronunciation: [sˈɛkəndəɹi pɹəθˈali͡əm] (IPA) 
The term "secondary prothallium" refers to the second stage of the life cycle in ferns, where a second generation of prothallium, or gametophyte, is produced. Synonyms for "secondary prothallium" include "secondary gametophyte" and "second-generation prothallium". This stage occurs after the initial prothallium, or primary gametophyte, produces sex organs that eventually form sporophytes. The development of a secondary prothallium is crucial in the reproduction of ferns as it allows for the production of more sporophytes, ensuring continued growth and survival of the species.
