Water is the source of existence for all living organisms. Plants cannot function without the moisture they need, it is required for many processes, including those that ensure their vital activity.

The simple combination of hydrogen and oxygen supports life on planet Earth. The existence of humans, animals, as well as plants will be threatened in drought conditions. Plants are composed of water and dry matter (everything else), and the water in them is not less than eighty percent. But even such a high moisture content is not enough to maintain vital activity, therefore, the process of its receipt from the outside is important. Plants use water for metabolic and physiological function. For example, transpiration together with evaporation takes up to ninety-eight percent of the incoming water. Transpiration is the process of building dry matter for the body of a plant using water; without it, vital activity is not possible. Thanks to her, the plant receives the necessary nutrients for growth and development, and also moves them and delivers them to the right place. Evaporation is designed to maintain thermoregulation, that is, prevent overheating, maintain the temperature within certain limits, and also prevent the destruction of proteins under the influence of high ambient temperatures. Chemical reactions in plants occur only in solutions, the main part of which is water. The process of photosynthesis is no exception - the formation of organic substances from carbon dioxide and water with the participation of chlorophyll contained in plants. Any plant that doesn't get the right amount of water will gradually fade away. Initially, it loses its attractive appearance, tissue elasticity. This happens because the lack of moisture forces it to concentrate all the vital forces inside (in the root system), without spending it on foliage. Further, the plant gradually dies, unable to receive nutrients and deliver them to their destination.
