Uses of Water in Plants

Water is substantial to the life of a plant. Water enables a plant to carry out its everyday processes to make sure it receives the necessary nutrients for development. Each kind of plant has its own necessary storage system to retain the moisture needed to adapt to its environment.

Support System

Plant tissues need water pressure in order for a plant to hold its support. The plant's cell wall has a vacuole which holds water that pushes outwards which keeps the structure of the plant from falling or wilting. A plant uses a special process called osmosis that transfers the water in and out of its cells.


Plants use water through a process called transpiration that allows it to cool itself by the water evaporating. This enables a plant's temperature to not rise too high. If a plant becomes too hot, the cells of a plant leaf will stop working, which can cause the leaf to die. Transpiration also uses the water to pull nutrients up from the soil with its roots.


Water is used for hydrogen during the process of photosynthesis and also keeps the plant from dehydrating. Photosynthesis is when a plant uses light, water and carbon dioxide to create energy and food. Water is also used to transport the nutrients throughout the plant and its cells.
