Photosynthesis system Photosynthesis system Photosynthesis systems are electronic scientific instruments designed for non-destructive measurement of photosynthetic rates in the field. Photosynthesis systems are commonly used in agronomic and environmental research, as well as studies of the global carbon cycle. Photosynthesis systems function by measuring gas exchange of leaves. Atmospheric carbon dioxide is taken up by leaves in the process of photosynthesis, where is used to generate sugars in a molecular pathway known as the Calvin cycle. This draw-down of induces more atmospheric to diffuse through stomata into the air spaces of the leaf. While stoma are open, water vapor can easily diffuse
Need for achievement do) assess such things as "creativity" in any general sense. One has always to ask "creativity in relation to what?" So McClelland's measures, originally presented as means of assessing "personality", are best understood as means of measuring competence in ways which break radically with traditional psychometric approaches. Everybody has different goals and needs for achievement based off many factors like past experiences, education, the risks, and the feedback they will receive. Need for achievement Need for achievement (N-Ach) refers to an individual's desire for significant accomplishment, mastering of skills, control, or high standards. The term was first used by Henry
