Installing rain gutters and collecting water from downspouts also helps reduce water use. Plant Needs for Water Water is a critical component of photosynthesis, the process by which plants manufacture their own food from carbon dioxide and water in the presence of light.
Water is one of the many factors that can limit plant growth.
Other important factors include nutrients, temperature, and amount and duration light. Water is also lost through the stomata in the process called transpiration. Transpiration, along with evaporation from the soil surface, accounts for the moisture lost from the soil. When there is a lack of water in the plant tissue, the stomata close to try to limit water loss. Wilting occurs when the tissues lose too much water.
