Guia morfológico de folhas: uma ferramenta pedagógica para o ensino de botânica

Abstract

This study aimed to elaborate a morphological guide of angiosperm leaves, systematizing their diagnostic attributes as both scientific and pedagogical tools for species identification in Amazonian ecosystems. The research was based on bibliographic review and field observations, addressing the main foliar characters (shape, margin, apex, base, and venation) and their taxonomic relevance. The analysis revealed that leaf morphological diversity reflects adaptive processes to environmental conditions, consolidating leaves as essential structures for botanical diagnosis in tropical environments. Beyond its technical-scientific contribution, the study sought to overcome the so-called “plant blindness” by transforming academic knowledge into an accessible didactic resource. The produced guide represents the culmination of this effort, offering descriptions and illustrations that facilitate species identification and enhance Botany teaching. In the school context, its application promotes active learning, stimulates ecological awareness, and values regional biodiversity. It is concluded that leaf morphology, combined with the production of contextualized didactic materials, fulfills a dual and fundamental role: strengthening botanical research and renewing teaching methodologies, turning species recognition into a meaningful and transformative experience inside and outside the classroom.
