Extração de pigmentos vegetais em aulas virtuais de fisiologia vegetal

Plant Physiology is the branch of botany that explores and studies vital phenomena for permanence plants in different environments, addressing interdisciplinary contents. One fundamental contents discussed photosynthesis, a process by which some other organisms transform light energy into chemical energy. This occurs photosystems, are made up accessory proteins pigments (chlorophyll a, chlorophyll b, β-carotenes xanthophylls). These pigments, when they receive sunlight, reflect colors may have specific functions, with paper chromatography technique being method extracting them. Knowing practical classes teaching learning process, this work aimed to use technique, widely used separate plant as an alternative photosynthesis during monitoring period at discipline higher education class, remotely. Green leaves were (student's choice); reddish/purple choice) or half beet; carrot, extract species. At end experiment, questionnaire was carried out where positive result obtained, according evaluation criteria established monitors, it possible obtain remote activities process. Through online classes, Vegetal capable contributing student can be out.
