KŘÍŽOVÁ, Simona
This bachelor thesis focuses on the issue of teacher personality in the context of preschool education, with an emphasis on their professional qualification, competencies, and the prestige of the profession. The theoretical part of the thesis examines various aspects of the teaching profession, including the history of teaching, the feminization of the teaching profession, the role of the teacher in the context of change, and the time demands of teaching. It also addresses the definition of competence and the professional skills necessary for effective teaching. Furthermore, the thesis analyzes the issue of planning the educational process, including the creation of school and classroom educational programs. The practical part of the work focuses on the objectives of the research study, research questions, and the methodology used to obtain relevant data. Furthermore, the results of the research study, which was conducted through a questionnaire, are presented and discussed.

The effect of nitrogen compounds in cultivation medium on growth and metabolism of tobacco plants
Křížová, Simona ; Ryšlavá, Helena (advisor) ; Synková, Helena (referee)
Availability of nitrogenic compounds in cultivation medium affects metabolism of plants. Plants Nicotiana tabacum L., Petit Havana SR1 were grown in vitro in Murashige- Skooge agar, with the lack of inorganic nitrogen in medium, with the organic nitrogen as the only source of nitrogen - amino acid glutamine or protein casein. I studied the activity of the enzymes related with the assimilation and metabolism of nitrogen (NR, GS, GOGAT, NAD+-GDH and NADP+-GDH) and also the enzymes of Hatch-Slack cycle (PEPC, NADP-ME, PPDK). These groups were grown in two varieties with or without the presence of 1,5% saccharose as an additional source of carbon. Plants stressed by the lack of nitrogenic compounds in medium showed a decrease in activities of all enzymes participating in nitrogenic metabolism and some enzymes of Hatch-Slack cycle (NR, GS, GOGAT, NAD+-GDH, NADP+-GDH, PEPC, NADP- ME) according to control plants. The only exception was PPDK whose activity slightly increased given the control plants. Casein as the only source of the nitrogen was metabolized, but plants grew slower than the control plants. Activities of all studied enzymes were lower the only exceptions were GS and NADP-ME whose activity increased. The utilization of glutamine by plants increased the activities of NR, PEPC, NADP-ME i PPDK...
