The effect of temperature on plant growth: teaching protocols of model experiments
Máhrlová, Zuzana ; Albrechtová, Jana (advisor) ; Mourek, Jan (referee)
This diploma thesis is focused on the creation of model tasks (by means of an experiment) for the study of biology at secondary schools and concerns the effects of temperature on plant growth. The selected tasks utilize the new didactic approach by means of the so called inquiry based education. This method of teaching contributes to the development of individual deduction reasoning and encourages the students to actively think about the subject matter. The thesis provides the necessary theoretical background for the topic together with the description of methods and material needed for the conducting the experiments. Furthermore, the thesis describes the necessary instructions and procedures to conduct the experiment and its use in the secondary school teaching practice and presents the requisite methodical guidelines and worksheets for them. Simultaneously, the thesis verifies the didactic applicability of the experiment and the worked out materials through a questionnaire survey and monitored application of the model tasks at secondary schools. The main result of this diploma thesis is a modern, functional and verified method of teaching for high school about the effects of temperature on plant growth in accordance with modern approaches to education, which include own experiments, their...

The effects of temperature on growth and photosynthesis of C3 and C4 in education
Máhrlová, Zuzana ; Albrechtová, Jana (advisor) ; Kutík, Jaromír (referee)
Photosynthesis, or photosynthetic assimilation, is a set of biochemical processes during which received light radiation energy is changed into energy of chemical bonds. To produce organic compounds, the photosynthesis uses as energy source only light energy and other sources of energy are CO2, mineral nutrients and water. The heat (infrared radiation) is one of the most important external environmental factors affecting plants. Too much of heat or its lack cause plant stress and influence all biochemical processes. Accordin, to the way of CO2 fixation, three types of photosynthesis can recognized- C3, C4 and CAM. Furthermore, C3 and C4 types of plants can be distinguished according to thein optimum temperature range, when C4 plants have optimum temperature ranges generally higher than C3 plants. Another differences between these types of plants consist in different physiological response to the changing climate, above all to the increasing concentration of atmospheric CO2 and simultaneously increasing temperature. The higher the concentration of CO2, the higher the rate of photosynthesis of C3 plants, whereas increased temperature increases the rate of photosynthesis of C4 plants. These different reactions of C3 and C4 plants on different environmental factors have consequences in a rate of net...
