Utilization of plant bioindicators in monitoring of environmental contamination
Koláček, Tomáš ; Vávrová, Milada (referee) ; Čáslavský, Josef (advisor)
Environmental contamination may be observed by different analytical tools as well as by various types of bioindicators providing relevant information about the effects of toxic substances and their mixtures towards organisms in situ. The aim of this work is to provide a comprehensive overview of plant bioindicators and biomonitors suitable for biomonitoring of persistent organic pollutants (POPs) in natural ecosystems. For groups of organic pollutants such as PCBs, PCDDs / Fs, PBDEs, PAHs, PFCs, and OCPs, review of literature is provided including knowledge about different species of coniferous trees, angiospermous plants (including crops), mosses and lichens that can be used for monitoring. In this work, analysis examples of samples of pine needles, bark, moss and lichen tissue are quoted as biomonitor tools. An overview of plants for phytotoxicity and genotoxicity observation using pollen grains abortivity and online bioindication as an example on non-specific biomonitoring is also provided.

Educative possibilities on flowers and fruits morphology in examples of important plant species
SLÁDKOVÁ, Eva
The diploma thesis follows up on the issues addressed in the bachelor's thesis. It focuses on the possibilities of teaching the morphological structures of flowers and fruits of flowering plants. The results are transformed into a form that can be used effectively in teaching. The work contains several teaching materials. Specifically, two chapters which introduce teaching presentations and worksheets on the topic of Flower and Fruit.

Teaching Angiosperms at Selected Primary Schools - Comparison of Ecological and Systematic Approach
Hypšmanová, Pavlína ; Skýbová, Jana (advisor) ; Brůnová, Linda (referee)
This diploma thesis entitled Teaching angiosperms at selected primary schools - comparison of ecological and systematic approach contains in the theoretical part a brief description of angiosperms and the most frequently mentioned families in textbooks for primary schools for better orientation. Furthermore, the work deals with two ways of teaching biology at primary schools - ecological and systematic approach, and the characteristics of teaching methods and organizational forms usable in the teaching of angiosperms. The thesis also includes an analysis of the topic in the new RVP for basic education, which reveals the deletion of two expected outcomes in the thematic area of plant biology compared to the older version of the RVP from 2017 and a comparison of two selected school educational programs. Part of the text is also an analysis of selected textbooks for primary schools with the topic of angiosperms, including comparison of the number of families and measuring the didactic equipment with a focus on the presentation of the curriculum. With the help of interviews with selected teachers, information about their approach to teaching and the implementation of teaching in the given concept is subsequently ascertained. Among other things, qualitative research focused on the perception of the...

Effectiveness of organism recognition using angiosperms as an example
Bukáčková, Alžběta ; Janštová, Vanda (advisor) ; Novotný, Petr (referee)
Students are less interested in science studies in this time. Yet, it is evolving and indispensable field (medicine, genetics). Various fields of biology students are evaluated differently. Botany is not very popular for students and often even for their teachers. More popular may be, for example, human biology, zoology and emerging fields such as genetics. Studying of plants isn't interesting for pupils, memories of learning about plants for them often spending hours with the botanical atlas without practical training in the field or on an excursion. There is a reason to writing this thesis about identification of angiosperms in high school. The thesis deals with different methods used for teaching identification of angiosperm plants at Prague high schools and their effectiveness. It compares the different methods used by teachers of these schools, focuses on with ways of testing plants cognition and the number of species that pupils should be able to recognize. The high school teachers' expectations are compared with the university teachers' expectations of the knowledge of incoming biology students. Effectiveness of teaching was tested by recognizing the required species. Students were asked to recognise the fresh plants. The success rate of students of teachers who use to teach different...

Reproduction of flowering plants and heat stress
Nedvědová, Kateřina ; Honys, David (advisor) ; Vítámvás, Pavel (referee)
This bachelor's thesis is a review summarizing the effects of heat stress on the reproductive development of flowering plants and their tolerance mechanisms. Plants are continuously exposed to changing environmental conditions and ever-increasing temperatures. Reproduction, especially the development of the male gametophyte, is particularly sensitive to these changes. This leads to defective development, sterile pollen, and fewer seeds, which affects crop productivity and yield. Therefore, it is essential to understand these changes, and especially the tolerance mechanisms. Keywords: reproduction, flowering plants, heat stress, tolerance, male gametophyte, female gametophyte

Didactic Utilization of Selected Angiosperms in Teaching at Elementary and High Schools
Moldaschlová, Jana ; Skýbová, Jana (advisor) ; Němečková, Linda (referee)
The diploma thesis deals with a didactic use of selected angiosperms in teaching at elementary and high schools. It provides theoretical knowledge concerning angiosperms, selected families, and plant species. Furthermore, it describes selected teaching techniques and methodology which can be used in teaching of the angiosperms. This thesis contains specific suggestions of the teaching methodology dependent on the selected plant families. A part of the thesis is a questionnaire survey, which contains the use of various forms and methods of teaching in natural science lessons at elementary schools and high schools. The results of the practical work are represented by practical exercises, worksheets and didactic games which teachers could use in teaching of the angiosperms. Key words: teaching techniques and methodology, questionnaire suvey, angiosperms
