项目摘要

Gas Exchange as a Primary Component of a Research-Oriented Biology Curriculum A new biology curriculum integrates project-oriented laboratories in all four years of the major to empower students with experience, confidence, and skills necessary to undertake independent research. A series of laboratory activities leads students through progressively more significant research experiences from introduction of biological concepts through guided design of their own experiments to development of research protocols. This series develops throughout three sequential courses: Frontiers in Biology, Organismal Biology, and Plant Physiology and prepares students for independent research projects involving organismal metabolism and gas exchange. Infrared gas analysis systems engage Frontiers in Biology students in the development of concepts in photosynthesis and respiration. Students in Organismal Biology use a diffusion phorometer and a portable photosynthesis system to investigate mechanisms of control of transpiration, factors that limit photosynthesis, and the effects of mineral nutrition on photosynthesis and transpiration. In Plant Physiology, students apply gas exchange techniques used in prerequisite courses to develop research protocols for investigating water use efficiency of desert shrubs, fruit ripening in native plants, and mechanisms of senescence in leaves.

气体交换作为一个主要组成部分的研究为导向的生物课程新生物课程整合了项目导向实验室在所有四年的主要授权学生有经验，有信心，有必要的技能，独立研究。一系列实验室活动引领学生通过逐步更重要的研究从生物学概念的引入到指导设计自己的实验，研究协议。这一系列的发展贯穿三个连续课程：生物学前沿，有机生物学，和植物生理学，并准备学生独立涉及生物新陈代谢和气体的研究项目交易所红外线气体分析系统生物学中学生概念的发展光合作用和呼吸作用。有机生物学专业学生使用扩散隐斜视计和便携式光合作用系统研究控制蒸腾作用的机制，限制了光合作用，以及矿物质营养的影响，光合作用和蒸腾作用。在植物生理学中，学生应用气体交换技术在先决条件制定水资源调查研究规程的课程荒漠灌木的利用效率，果实成熟在本地植物，以及叶片衰老的机制。
