How does this happen?
It might seem like magic but as a science pro you will know … Plants “drink” water from the ground through their roots. The water travels up the stem of the plant into the leaves and flowers. When we cut a flower off the plant it can’t get water from its roots any more but its stem can still drink! Inside a stem there are bundles of tiny drinking straws (called xylem). As the water evaporates from the surface of petals and leaves, the water behind is ‘sucked’ up inside the xylem. And if we put dye in the water, the dye gets sucked up too. This water movement through tiny tubes is called capillary action.
