The study, photosynthesis and the study of the impact of the topical laboratory activities related to respiratory issues in plants on the conceptual understanding of the teaching candidates. For this purpose, the research was carried out in the spring period of the 2016-2017 educational year, in the framework of the General Biology Laboratory Applications course, with the processing of photosynthesis and the respiratory issues in plants in the form of supercarb laboratory effects throughout a period with the Science Knowledge teacher candidates (N:34) . A single group of pre-final test models were used in the study. In the study, the data was gathered with "Photosenthesis and Plant Respiratory Concept Test" and "Open-Full Questions". The data obtained is analyzed by imagistic analysis technique. The research has found that the use of top-floor laboratory activities in biology laboratory applications has developed the teaching candidates' conceptual understanding of the relevant subject and has fixed the conceptual errors. In this regard, the teaching of abstract and difficult to understand concepts in the biology laboratory applications is recommended to activate students’ supernova with activities such as the creation of concept maps, poster preparation, class and group discussion related to experiments and daily writing.
