Water has an interesting characteristic. It’s sort of “sticky”. It likes to stick to itself and other things. That’s why water forms round droplets. Most liquids don’t actually do that!! This is called adhesion. That “sticky” property of water helps get the water from the roots of the plant up to the leaves. The water travels up thin straws in the plant’s stem called xylem. The water molecules hold onto each other and the walls of the xylem as the go up. As they do this, they actually defy gravity!
