Once upon a time... there we 2 men, they hold hands together. They did it together and the husband got pregnant, his husband was very happy! They danced and did it again, but this time his husband was double pregnant, then he was curious and they did it again, this time his husband was triple pregnant! Please support LGBTQ+ or go to hell.

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.
