Why do plants need water? MPX STEM

After working on the infographic with my teammates, it really gave me a different perspective on why plants need water. Before I thought that plants only needed water because it was essential to keep it alive. I generalized it like how I think of humans needing water. But it is actually much more complicated than that.
    First off all, water is needed to keep the plants shape. Plants bodies are much more dependent on water than human bodies. If they lose water, the plant will lose its shape. Water is also needed for making food for the plant. Photosynthesis cannot be preformed if the plant does not have water.
   The way water goes through plants is almost exactly like the water cycle. It rains, which then soaks the ground an gets absorbed by the plant, which passes through it body and goes back up into the sky. This cycle, if consistently working, will make the plant flourish. But, the cycle will not always work, because it is not consistently raining, and there are too many variables involved. Plants must be resilient, which leads to plants evolving to fits its needs. For example, if the cactus wasn't able to hold water, there would be no way it would be able to survive in desserts.
   My understanding of plants, because of this project, has flourished. I will never look at plants the same as I did before. They need water as their first necessity in a sense, because it gives them shape, and lets them create food for themselves.
