Each water molecule pulls on the lower water molecule by being hydrogen bonded, one to another molecule. So, this works somewhat as a chain, along with the other forces in play here, to move water molecules up the trunk and into the leaves of the tree.
Transporting water molecules up high in tall trees is done with cohesion along with adhesion of water creating a column of water in the xylem(tube) of trees helping push it upward to the leaves up high. This is helped by evaporation.
B. Capillary action. Capillary action, along with cohesion and adhesion forces, allows water to move upwards through the xylem in the tree, from the roots to the leaves. These forces help counteract gravity and allow water to reach the top of tall trees.
The property of water known as cohesion helps plants transport water from their roots to their leaves. Cohesion is the tendency for water molecules to stick together, allowing them to move as a continuous column through the plant's vascular system.
Water is transported to the leaves of tall trees through a process called transpiration, which is driven by the cohesion and adhesion properties of water. Cohesion allows water molecules to stick together, forming a continuous column in the xylem vessels of the plant. Adhesion helps water molecules adhere to the walls of the xylem vessels, aiding in the upward movement of water against gravity. This cohesive and adhesive property of water allows for a continuous flow of water from the roots to the leaves of the tree.
The force that moves water from the roots to the leaves in plants is called transpiration. This process is driven by a combination of factors, including evaporation from the leaves, cohesion and adhesion of water molecules, and the tension created in the xylem vessels.
Transpiration. The water is leaving the leaves by the stomata and water is a polar molecule that is hydrogen bonded, one molecule to another. This cohesion allows the molecules of water to pull other molecules up the tree as they leave into the atmosphere through the stomata.
Capillary action & osmotic pressure.
The cohesion-tension theory explains how water is moved from roots to leaves in plants. This theory suggests that water is pulled up through the plant by the cohesive forces between water molecules and the tension generated by transpiration in the leaves. This creates a continuous water column that is pulled up through the xylem.
Cohesion

The xylem is responsible for transporting water from the roots to the leaves in an angiosperm plant. It is a vascular tissue that forms tubes to conduct water and minerals throughout the plant.
both have specialized channels for transporting water.
Cohesion
Because of its polarity, water has the unique property of being able to creep up thin tubes. Plants in particular take advantage of this property, called capillary action, to get water from the ground. This is how water can reach the tops of trees. :D
