生物生理学（Biological physiology） Examination outline of Plant Physiology I. the nature and requirements of the course This course is a specialized basic course. It is the study of the law and essence of plant life activities. Through the study, the basic concepts require candidates to have plant physiology and basic theoretical knowledge, understand the basic rules of plant life activities, understanding the physiological process and the nature of plant growth and development, so that reasonable use of light, temperature, gas, water and soil resources, with agricultural production, improve the analysis and solve problems ability. Two, the course content and requirements Chapter 1 water metabolism in plants (1) the important physiological significance of water 1. grasp the important physiological significance of water in plant life. 2. to master the existing state of water in plants and its influence on metabolism. (two) the principle of water absorption by cells 1. master the concept of water potential. 2. master the composition of plant cell water potential. 3. master the principle of water absorption by cells and the law of water movement. (three) principle of plant root water absorption; 1. master the power of root water absorption (transpiration, root pressure). 2. understand the external factors that affect plant root water uptake (soil temperature, soil solution concentration, and soil aeration conditions). (four) transpiration of plants 1. understand the significance of transpiration 2., grasp the indicators of transpiration (transpiration rate, transpiration efficiency, transpiration coefficient). 3. understand the influence factors of transpiration (temperature, air humidity, wind speed, light intensity, etc.). 4. master the way of water transport in plants. (five) physiological basis of reasonable irrigation (including indexes, methods, etc.) The second chapter is about the mineral nutrition of plants (1) essential mineral elements of a plant 1. what are the n
