Plant physiology is a subdiscipline of botany concerned with the functioning, or physiology , of plants. Fundamental processes such as photosynthesis , respiration , plant nutrition , plant hormone functions, tropisms , nastic movements , photoperiodism , photomorphogenesis , circadian rhythms , environmental stress physiology, seed germination , dormancy and stomata function and transpiration , both parts of plant water relations, are studied by plant physiologists. The field of plant physiology includes the study of all the internal activities of plants—those chemical and physical processes associated with life as they occur in plants. This includes study at many levels of scale of size and time. At the smallest scale are molecular interactions of photosynthesis and internal diffusion of water, minerals, and nutrients. At the largest scale are the processes of plant development , seasonality , dormancy , and reproductive control. Major subdisciplines of plant physiology include phytochemistry the study of the biochemistry of plants and phytopathology the study of disease in plants.

Plant physiology. L Taiz, E Zeiger. Plant physiology is part of the essential core curriculum every botanist has to master. Physiological adaptations play as great a role in the evolutionary struggle for life of a plant as morphological ones. The book is subdivided into 25 chapters, grouped into three larger sections water, metabolism and development that cover the major topics of modern plant physiology.
