From an young age you learn to water plants and the grass to keep it green and healthy. I know other factors such as soil and nutrients play a big role but why specifically is water needed for this?

Answer 1

The O2 that plants release as a product of photosynthesis comes from the water the plant takes in. (The CO2 the plant inhales is not the source of oxygen that it exhales)
