The structure of a holistic plant is studied on a basis of results of examinations of analogical structures. A proposal of an experimental approach for verification of holistic principles in the plant is submitted – a structural model of events. In contrast with e.g. animals the control system of a plant is distributed. There are no specialized organs for individual parts and functions of the control, but the system inside cells is used. Thanks to a relatively simple and stabile structure of a plant, at least qualitatively, an environment is formed aggregating partial and substantial influences around certain cells. Thus at the time of solving its environment the system of control of these cells solves also substantial environment of the plant as a whole. Afterward this solution is humorally transformed into the structure of the entire plant.
