Importance of Water to Plants

...

Every living thing requires water. Plants can use up to its entire body weight in water. If humans were to use the same amount of water, we would need to drink up to 20 gallons of fluid a day.

Function

...

Plants use water to dissolve minerals and nutrients from the soil surrounding the root system and carry it up through the stems and leaves.

Transpiration

...

Water is essential for transpiration, the exchange of water for carbon dioxide. Pores in the leaves of plants absorb carbon dioxide and allow water to evaporate out.

Structure

...

Water fills the cells of plants providing firm support. This is why plants wilt when deprived of water and perk up after receiving water.
