Plant physiologists study fundamental processes of plants, such as [[photosynthesis]], [[cellular respiration|respiration]], [[plant nutrition]], [[plant hormone]] functions, [[tropism]]s, [[nastic movements]], [[photoperiodism]], [[photomorphogenesis]], [[circadian rhythms]], [[environmental stress]] physiology, seed [[germination]], [[dormancy]] and [[stoma]]ta function and [[transpiration]]. Plant physiology interacts with the fields of [[plant morphology]] (structure of plants), plant [[ecology]] (interactions with the environment), [[phytochemistry]] ([[biochemistry]] of plants), [[cell biology]], genetics, biophysics and [[molecular biology]].
