Abstract
Plant biology, mainly plant anatomy, is a less attractive area for students at high school and university, but not much research has been devoted to improve this field. We therefore researched into the teaching of root, stem and leaf anatomy combined with the preparation of native microscopic slides and histochemical reaction using two selected dyes (classic phloroglucinol test combined with textile dye ‘Duha green’ to visualize xylem and phloem, respectively). The use of reagents in teaching had a positive effect on students’ knowledge (control/experimental class) of root (+70%), stem (+70%) and leaf anatomy (+130%) as well as vascular and mechanical tissues (+170%), leading to an overall improvement of knowledge by ca. 100%. Students’ ability to identify individual tissues on microscopic slides increased and they also understood the functions of individual tissues after self-preparing and staining slides. However, we identified that some aspects were still problematic for students after the experimental education (e.g. identification of tissue providing secondary growth, significance of sclerenchyma and transpiration). We also attach correct answers for the anatomy test and worksheets used for practical exercises as motivation for wider use to improve students’ knowledge of plant anatomy.
