Substances Contained in Plants of the Nightshade Family (*Solanaceae*) and their Usage in Biology Teaching
Marečková, Michaela ; Skýbová, Jana (advisor) ; Pavlasová, Lenka (referee)
The aim of the thesis titled "Substances contained in Plants of the Nightshade Family (Solanaceae) and their Usage in Biology Teaching" is to familiarize the reader with basic toxicological and pharmacological terms contained in the information on Nightshade plants (Solanaceae). Further it introduces Nightshade plants (Solanaceae) and their substances in more detail. It describes the use and abuse of these plants in poisoning, usage in traditional medicine, homeopathy and modern medicine. It outlines the history of the use and especially abuse of plants containing alkaloids. It also describes options for didactic use through laboratory work and assesses and compares the quality of information available in the literature for high school students. Information contained in this work can be practically used in teaching subjects such as toxicology, pharmacology and pharmacognosy at secondary schools with focus on the chemical and pharmaceutical industry. Key terms: Content Substances, Plant Alkaloids, Poisonous Plants, The Use and Abuse of Solanaceous Plants.

Toxic plants in teaching of biology at secondary schools
Riegelová, Marta ; Rajsiglová, Jiřina (advisor) ; Chlebounová, Irena (referee)
This diploma thesis is dedicated to teaching botany, and is focused namely on lessons concerning toxic plants. The first part deals with creating of worksheets for secondary school students for field trip into Botanic Garden of Faculty of Science, Charles University in Prague. The second part compares effectiveness of classical lesson and the field trip. Students of the first grades from four secondary schools (grammar schools) were divided into two groups.The first group was taught by classic conventional teaching in classroom (control group) and the second group (experimental) was taken for the field trip to the Botanic Garden of Faculty of Science, Charles University in Prague. The effectiveness of education was measured by means of a knowledge test before the lesson (pre-test) and after it (post-test). Level of knowledge increased in experimental groups and control groups, however, the difference between individual groups was not significant. Key words: toxic plants, botanical garden, field trips, worksheets, knowledge testing

Killer plants in Prague and its surroundings: A guide to their diversity and hidden dangers
Kováříková, Kateřina ; Slovák, Marek (advisor) ; Novotný, Petr (referee)
The immobility of plants and their inability to escape from danger is compensated by the creation of various defence strategies, which are used mainly by toxic plants. The main goal of the bachelor's thesis is a literature review on the topic of poisonous (toxic) plants, both in the context of defence mechanisms and their importance for human society. The thesis deals with the description of the main groups of toxic plant compounds, summarizes their chemical composition, properties, distribution, and effects on the human body. The second half of the work is focused on the diversity of wild-growing but also of some cultivated toxic plants of our landscape with a specific focus on the flora of Prague and its immediate surroundings. It analyzes plant representatives from two families, important for the production of toxic secondary metabolites, in more detail. Specifically, they are the aubergine (Solanaceae) and buttercup (Ranunculaceae) families. Along with the description of partial representatives, their distribution, ecology, my work also describes the documented poisonings and use of poisonous plants in folk and modern medicine. The impetus for the creation of this work is the low awareness not only of the child population but also of adults, about the dangers, risks, and impact of these toxic...

Plants containing toxic substances in the garden of nursery schools
Pilařová, Kateřina ; Pavlíková, Daniela (advisor) ; Jitka, Jitka (referee)
This thesis is focused on the occurrence of poisonous plants in gardens of nursery schools, assesses the level of danger to children and awareness of teachers who ensure the safety of children during their stay in the nursery schools. Attention is paid to individual groups of plant toxic compounds. Reactions of the organism to their presence, including examples of poisoning caused some of them, and a first aid for intoxications are discussed. Mentioned are the most dangerous plants with possible occurrence in our geographical conditions, and esp. those that can entice children by an attractive appearance of some of their parts (flowers, fruits, etc.). It also includes a statistical analysis of the incidence of poisonous plants in gardens of nursery schools and the awareness of educational supervision. The conclusions of the investigation indicates that in gardens of nursery schools are often found large quantities of various dangerous plants containing toxic substances and children use for their games some parts of such plants. Although the evaluation of the actual toxicity of the plants is very difficult, there's no space for underestimating this danger and it is appropriate that teachers recognize poisonous plants. Toxic plant substances have high biological activity in low doses. This work should serve as a basis for creating material for purposes of public health surveillance in schools and school facilities and manuals directly for the needs of schools, because gardens of nursery schools are due to young age, intellectual capacity and a high number of children the riskiest place for the possibility of poisoning.
