Educational Application for Learning about Plants
Nedělová, Markéta ; Tesařová, Alena (referee) ; Hynek, Jiří (advisor)
This work focuses on the design and implementation of an interactive educational application that could help students master the learning of plant species through elements of gamification. To address this problem, a progressive web application was designed and implemented. This application was created in response to the requirements and needs identified during cooperation with the Primary School in Olešnice. It allows students to practice and expand their knowledge of plants through quizzes.

Corpus, Corporeality, Carnality
Lienerová, Lucie ; Čech,, Viktor (referee) ; Fexová, Patricie (advisor)
The subject of the diploma thesis is corpus, corporeality and carnality inspired by Ovid's Metamorphoses. The practical outcome is a series of paintings, drawings and objects thematizing the particular parts of the transformation of human, object and environment into individual organic forms. The transformation of the human being itself is seen as a painful process, but one that also allows for liberation from much more extensive physical and psychological suffering. The motifs of transformation are shaped and documented in a painterly way on the artist's close person and then on the environment and objects that surround this person.

Didactic games on the topic of plants in primary school teaching
BÁROVÁ, Lucie
The aim of the diploma thesis was to create a set of didactic games on the topic of plants suitable for teaching children at the first grade of primary school. The games were created to acquire new knowledge and deepen the already acquired curriculum. The games are focused on the subject matter of plants and are created in accordance with the curriculum documents. The designed games can be implemented in nature, in the classroom and in the school garden. Some of the proposed games have been verified in practice at a primary school in the South Bohemian Region.

Design of watering module for mobile robot
Vizváry, Peter ; Králík, Jan (referee) ; Krejsa, Jiří (advisor)
The diploma thesis is focused on the design of a watering module for a mobile robot. The main goals of this work are to design various concepts of the watering module and their subsequent comparison, ending with the selection of the final concept, which results in its implementation in the form of a prototype with subsequent testing of its properties. The first part of this work is focused on the analysis of the issue and the definition of the assigned task together with the main parameters and requirements. The second part contains an overview of known solutions to the issue and designs for own concepts of the watering module and its individual components. The designs are compared and evaluated in terms of their performance, complexity and price. In the third part, based on the evaluation of the most promising variants, there is a selection of the final concept and after that designing and selection of the final constructional solution. The fourth part is focused on the design and implementation of the prototype, contains the selection and design of the necessary components, module assembly and the creation of the control algorithm of the watering module. The final fifth part contains testing of the functional properties of the prototype, their evaluation and subsequent suggestions for its improvement.

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.

The role of alternative splicing in plants
Földi, Marek ; Klodová, Božena (advisor) ; Fischer, Lukáš (referee)
Alternative splicing is a mechanism of gene expression regulation that maintains, regulates, and creates genomic diversity and tissue specificity in plants. It involves the differential joining of exons in precursor mRNAs, leading to multiple mRNA isoforms from a single gene. The formation of these isoform variants and their subsequent translation leads to subfunctionalization of proteins, generating diversity in structure and function. Therefore, alternative splicing is often important in various biological processes in plants, such as development, stress response, immunity, and reproduction. Key types of alternative splicing events include intron retention, exon skipping, alternative 5'/3' splice sites, and mutually exclusive exons. Regulation of alternative splicing involves cis-regulatory elements and trans- acting protein factors such as serine/arginine-rich (SR) proteins and heterogeneous nuclear ribonucleoproteins (hnRNPs). This thesis aims to summarise the mechanisms and consequences of alternative splicing in plant development, including maturation of male and female gametophytes, meiosis, stress, and cell differentiation. It also describes methodological approaches that allow for a genome-wide study of alternative splicing, including microarrays, RNA-seq, and PCR. A better understanding of...

Physiological responses of plants to arficial light
Holečková, Barbora ; Münzbergová, Zuzana (advisor) ; Konrádová, Hana (referee)
The topic of this bachelor`s thesis is the physiological response od plants to artificial lighting, meaning artificial lighting from street lamps, which is one of the important anthropogenic influences. Artificial lighting at night is referred to by the acronym ALAN (from the english phrase Artificial light at night) and can have a significant effect on plant behaviour. In this thesis, the current knowledge on the influence of streetlights on not only plant behaviour but also on entire ecosystems is summarised in the theoretical part. In the practical part, the chlorophyll content of plants is measured, which is an important parameter informing about their physiological state, i.e. whether nighttime artificial lighting has an influence on it. Subsequently, the detected chlorophyll content of plants under street lighting is compared with that of paired control plants in their surroundings that are not under any artificial lighting. The measurements are carried out using a specially designed instrument for the detection of chlorophyll content in plant leaves called CCM300. The result of the work is the understanding of the possible effect of street lighting Key words Physiological reaction, artificial light at night, plants, chlorophyll
