If a plant with reddish leaves were used in a similar experiment , how might the results differ ? explain

Well if you put one of the leaves in some chemicals and another leaf in some water one of them might die and the other one might turn green or something like that

By water evaporation from the leaves is created a negative pressure at the top of the tree that promotes the ascension  of the water through channels that are called xylem. there are also two molecule forces that are involved: the intra-water molecules cohesion (water molecules stick to each other) and the adhesion when the water molecules stick to the channels they are running in. this is what enables water to go from the roots to the top of a tall tree.
