Physiology

 1.     : Plant physiology could be a subdiscipline of biological science involved with the functioning, or physiology, of plants. Closely connected fields embody plant morphology, plant ecology, phytochemistry, cell biology, genetics, physical science and biological science. Plant physiology could be a sub discipline of biological science involved with the functioning, or physiology, of plants. Closely connected fields embody plant morphology (structure of plants), plant ecology (interactions with the environment), phytochemistry (biochemistry of plants), cell biology, genetics, physical science and biological science elementary processes as chemical action, respiration, plantnutrition, phytohormone functions, tropisms, nastic movements, photoperiodism, photograph ontogenesis, unit of time rhythms, environmental stress physiology, seed germination, dormancy and stomata perform and transpiration, each elements of plant water relations, area unit studied by plant physiologists. the sphere of plant physiology includes the study of all the interior activities of plant those chemical and physical processes related to life as they occur in plants. This includes study at several levels of scale of size and time. At the littlest scale area unit molecular interactions of chemical action and internal diffusion of water, minerals, and nutrients. At the most important scale area unit the processes of plant development, seasonality, dormancy, and generative management. Major sub disciplines of plant physiology embody phytochemistry (the study of the organic chemistry of plants) and phytopathology (the study of malady in plants). The scope of plant physiology as a discipline could also be divided into many major areas of analysis.
