I'm doing an experiment on the water intake of plants and need to know what plant would be the best to use.

OK, I don't know how old you are, but I remember an old one from when I was a child. Take a white carnation, and split its stem up the middle. Fill two beakers with water, add food dye in contrasting colors to them (red and blue is good), and put half of the stem in each beaker. In no time at all you will have a custom-colored carnation.
Of course, it really does illustrate the water intake of plants, especially since this is a cut flower. It makes the point that it's not just the roots, but all along the stem, and that a plant does not die quickly when it is separated from its roots, because the cells live on. If they can get the nutrients they used to get from the roots, they are fine for awhile. If they can grow new roots (many can, just in water; sweet potatoes are the classic), they can start their whole life cycle over without having to go through the seed in the soil routine.
