In botany, water is mainly used during the irrigation process to provide the adequate hydration and nutrients to the plants. Without water, plants ultimately dry up and die. It is possible to re-hydrate a dried-up plant by gradually providing it with the right amount of water until it is nursed back to health again.

Additionally, plants require water during the process of photosynthesis to help them produce their food. Water moves up the plant’s stem and moves up to the leaves. Once it is evaporated, water leads to carbon dioxide, which feeds the plants. This particular exchange of water and carbon dioxide is what causes dew on the surface of the plant.

On the other hand, too much water can have an adverse effect on the plants because it stifles the roots and prevents adequate oxygen absorption, which causes the roots to writher up, rot, and die. Consequently, gardeners often install a drainage system to keep excess water at bay.

Water can take several forms: liquid, gas, and ice. In nature, it is more commonly seen in liquid and ice form.
