Some plants are composed of up to 95 percent water. Water is vital from the moment seeds are sown through sprouting to the end of the growing season. Plants need water for cell division, cell enlargement, and even for holding themselves up. If the cells don’t have enough water in them, the result is a wilted plant. Water is essential, along with light and carbon dioxide, for producing the sugars that provide the plant with energy for growth. It also dissolves fertilizers and carries nutrients to the different parts of the plant.
