I'm assuming you meant "why", not "what".
All organisms (living things) need water to survive, not just plants. Water serves many functions in plants, including as a part of chemical reactions that make sugar from sunlight and air (photosynthesis), as well as energy from sugar (cellular respiration). It's used in the process of hydrolysis to digest food in the stomach, and many vitamins need to be dissolved in water in order to be absorbed. It also makes up the majority of fluids inside cells and between them.
Water is used in plants, like all other organisms, for osmosis, which is a natural occurance that keeps the makeup of a solution on both sides of an obstacle (in this case, the cell membrane and cell wall) even. In plants, because of the stiff cell wall, the water creates pressure called turgor pressure, which is how plants manage to stay up (think about an inflated tire).

∙ 10y agoOh yes, every type of plant needs water, as do all other types of living organisms that we know of, here on Earth, but they do not all get their water by the same methods. Some plants can actually utilize water vapor from the air, rather than having to absorb water through roots. But all plants need water.
