Well, it's not really a tube. It's more like a stack of cells in a column, and the water moves along by being transferred from cell to cell. If you want to learn more about this transfer, called capillary action, try this website: - 7k

What are leaves for?

Plants use a process called photosynthesis in order to change sunlight into food. This process takes place mostly in the leaves of a plant. Leaves are large and flattened so that a large area of chlorophyll is exposed to the sunlight. Leaves are also used in a process called transpiration, which helps draw water and dissolved minerals up the plant's stem from the roots, where these substances have been absorbed from the soil. During transpiration, water evaporates through tiny holes in the leaves. More water is drawn up through a thin tube extending down the plant's stem.

How does water enter leaves?

Water enters the root cells by osmosis and enters into the xylem. The pressure of water entering the xylem creates osmotic pressure, pushing the column of water up through the stem. Water evaporating on the surface of the leaf cells pulls on other molecules and pulls the column of water up the plant and into the leaves.
