Abstract

GANIKO-DUTRA, Matheus et al. There is no hermaphrodite flower: an investigation of the terminology used for the reproductive structures in the alternation of generations of Angiosperms. Ciência educ. [online]. 2022, vol.28, e22056.  Epub Nov 17, 2022. ISSN 1980-850X.  https://doi.org/10.1590/1516-731320220056.

Assigning sexual nomenclatures to plants or structures in the sporophyte phase of angiosperms, as in the term hermaphrodite flower, is a recurring practice in the teaching of Botany and may cause misunderstandings. This work aimed to identify the compatibility in textbooks of higher education and in scientific papers, between the nomenclatures of the reproductive structures of angiosperms with the life phases and then classify such terms according to their likelihood to cause misunderstandings. We created a list with the main nomenclatures of the reproductive structures of angiosperms and, based on it, we carried out a categorial analysis of the textbooks and papers. The results showed lack of standardization, as the same textbook or paper sometimes uses a sexual nomenclature referring to the sporophyte, and sometimes it does not assign sexuality to it. Therefore, we recommend a standardization and unification of the terms, namely, using a proper nomenclature of a structure according to the life phase of the plant and using an exclusive term for each structure.

Keywords : Botany teaching; Higher education; Textbooks; Angiosperms; Spore reproduction.
