water has a property called "cohesion and adhesion" which make molecules of water sort of stick to each other because of waters polarity
dnn is wrong, the attraction between water molecules is LESS than their attraction to the sides of the vascular system of trees. It’s called capillary action. This is why you can see a meniscus (curved surface of water) in a small tube. The water climbs up the sides of the tube. This is also how sponges absorb water, etc…
