Physiology (Greek phýsis = nature, lógos = teaching) is the study of the fundamentals of life processes, in particular the life processes and functions in an organism. It is a branch of biology. Physiology encompasses biophysical processes in the cells, tissues and organs of all living organisms in the interaction of all physical, chemical and biochemical processes.
In a plant such as the vine, it includes the central life process of photosynthesis (image) and the communication between cells, tissues and organs. This includes nutrient uptake, water balance, transpiration (evaporation), respiration (breakdown of glucose to produce energy for cellular processes), all growth processes (controlled by plant hormones such as auxins, gibberellins and cytokinins) and reactions to environmental stimuli (adaptation to light, gravity, touch and other environmental factors).
Serious sources on the internet are rare - and Wine lexicon from wein.plus is one such source. When researching for my articles, I regularly consult the wein.plus encyclopaedia. There I get reliable and detailed information.
