This film, from Twig World, explores how plants transport resources via the xylem and phloem. The key points made in the the film are: •Transpiration is the evaporation of water from leaves into the atmosphere. •It causes water to be sucked up from roots to the leaves. •Water enters the roots from the soil by osmosis. •The xylem and phloem are systems of hollow tubes that carry the water and food.
