CITES plants in cosmetic products
JAKUBCOVÁ, Claudia
This thesis deals with the properties of endangered plant species listed in CITES Appendices that are contained in cosmetic products on the Czech market and the characteristics of these products. The attitude and responsibility of companies towards environmental protection issues and the evaluation of these cosmetic products by users were investigated by questionnaires. A total of 20 species were found in 90 cosmetic products, of which 12 representatives were from the family of Orchideaceae, two species of cacti (Selenicereus grandiflorus, Opuntia ficus-indica), ginseng (Panax ginseng, Araliacae), Aloe ferox (Asphodelaceae), Euphorbia antisyphilitica (Euphorbiaceae), Aniba rosodora (Lauraceae), Aquilaria malaccensis (Thymelleaceae), Cyathea medullaris (Cyatheaceae). No cases of collection in the wild were found. All the evidence shows that the plants used in cosmetics are cultivated and therefore the CITES Convention is not violated. Users were satisfied with the cosmetic products.

Proposal of project based education on the topic of air-conditioning function of vegetation in the landscape
ŽEJDL, Matěj
As part of this work, the role of the regional vegetation in the water cycle was designed in the project of education. The project was made in a try of the praxis. A part of the education is measuring air temperature and the relative air humidity in the different habitats. Due to this measuring primary school students can see differences between habitats and they can think about the meaning of the project education in the role of the differences in the vegetation and in which way flora is influencing the water. The work is focused on the research of the meteorological and biological conditions suitable for education project management. Work also briefly sums the role of respondents in the Biology lessons and their knowledge of the examined topics made during the lectures. The finding of the primary school student's knowledge was done with the use of questionnaire.

Plants as model organisms in inquiry science education in primary education
JINDROVÁ, Aneta
Research-oriented teaching is an attractive way of teching (not only) science subjects. At the first stage of primary school, it is an opportunity for developing students' research abilities. Plants are a suitable subject with which simple experiments, observations and research activities can be performed. The aim of the work is not only to find the possibility of using plant material in students' science research during teaching, but also to evaluate how research activities are accepted by students, how they are able to solve problems and how creative they are in solving research tasks. The work should show the possibilities of combining standard tasks based on plant observation with tasks based on different levels of research activity. The diploma thesis is divided into a theoretical and a practical part. I approached this thesis in four steps. In the first step the curriculum and content of selected textbooks are analyzed with a focus on the issue of learning about living nature, in the second step the educational offer is presented, in the next step the proposed educational offer is verified with simultaneous monitoring and analysis of students 'research tasks and pupils' creativity. In the last step, the results of the survey are evaluated and the obtained data are interpreted. The diploma was drawn up as part of a project GAJU 123/2019/S.

The use of Natural Materials in Primary School Education
BARTOŠOVÁ, Martina
The theme of this diploma thesis is Natural materials in the subject of Craft at primary school (at the first level of the elementary village school). The aims and tasks of the diploma thesis are defined in the introduction. The theoretical part is devoted to concepts, goals and output competences in technical and environmental education at the first level. It deals with the description of well-known and lesser-known nature materials and the characteristics of various natural techniques when working with natural materials. The description of the elementary school in the village of Malonty is the integral part of the theoretical text. In the practical part, ten didactic themes for working with natural materials are proposed. Some of them were realized in practice and their effectiveness was verified through questionnaires for children.

Heat-shock proteins and plant tolerance against high temperature stress
Ott, Kristián ; Hála, Michal (advisor) ; Konrádová, Hana (referee)
In context with ongoing climate change, the average temperature is still rising. This is a problem mainly for agriculture and production of groceries, because plants generally have difficulties when coping with ambient temperature higher than 40 řC. If there would be continuing trend in decrease of global food production, it could cause problems with feeding still growing world population. Organisms in general developed many mechanisms of stress adaptation. One of these evolutionary adaptions to high temperature stress is production of heat shock proteins (HSPs). HSPs are very conserved family of proteins present in both prokaryotes and eukaryotes. This thesis summarizes present knowledge about the HSPs and their function (not only) during the high temperature stress in plants, but some of the information presented in this thesis were obtained also from other organisms. The thesis starts with general introduction to the high temperature stress and how plants can sense the ambient temperature. Next is general mechanism of induction of HSPs and their classification, structure, and mechanism of action. The possibility of future use of HSPs in agriculture and medicine is opened in last chapter.

Electrophoretic determination of oxidized and reduced form of glutathion in plant material
Durychová, Eva ; Křížek, Tomáš (advisor) ; Kubíčková, Anna (referee)
This work is based on a previously published method for the determination of twenty proteinogenic amino acids by capillary electrophoresis with contactless conductivity detection and deals with possibility of its use for the determination of oxidized (GSSG) and reduced (GSH) forms of glutathione with amino acids. The theoretical part firstly deals with brief introduction of the properties and importance of glutathione and its protection against autooxidation, especially by alkylation with N-ethylmaleimide (NEM), which binds to GSH to form its alkylated form (GSH-NEM). Then, a brief summary of the available methods for determination of glutathione is given, with a focus on the already developed capillary zone electrophoresis methods. Finally, it briefly presents the electrophoretic method for the determination of twenty proteinogenic amino acids on which this work is based. In the experimental part, the integration of the determination of both forms of glutathione into the method for the determination of proteinogenic amino acids is presented. First, a simplified, less time consuming method was tested in shorter 50.0 cm capillary without hydroxyethylcellulose, where both forms of glutathione were separated at baseline within 10 minutes. Relative standard deviations of peak areas (GSH 2.1%; GSSG...

Preparation of microbial, plant and algal extracts to use in cosmetics for infants
Janderová, Šárka ; Dzurická, Lucia (referee) ; Márová, Ivana (advisor)
This bachelor thesis deals with the preparation of a cosmetic product for infants with the addition of active substances from cyanobacteria, microalgae, or plants. In the theoretical part, a review was made, which not only summarizes the basic information about these organisms, but also the antioxidants contained in these microorganisms. In the practical part, several types of extracts from cyanobacteria, algae and plants were prepared and characterized. The content of phenolic substances, chlorophylls and content of carotenoids were measured spectrophotometrically. Content of soluble proteins was determined by Hartree-Lowry method and the fatty acid profile in biomass was obtained by GC. Furthermore, the SPF factor was measured using the spectrophotometric method the Mansur equation. Antioxidant activity was determined by using the TEAC method. Finally, two of the best extracts were selected for the preparation of cosmetic emulsions. The sensory analysis of prepared emulsions was performed for the period of two weeks.
