Transport of nutrients and water in Plants

Transport of nutrients and water in Plants. A review. The conduction of water and nutrients. Sugars are conducted throughout the plant in the phloem, water and other nutrients through the xylem. Conduction occurs from a source to a sink for each separate nutrient.

  3. Theconduction of water and nutrients • Sugars are conducted throughout the plant in the phloem, water and other nutrients through the xylem. • Conduction occurs from a source to a sink for each separate nutrient. Sugars are produced in the leaves (a source) by photosynthesis and transported to the roots (a sink) for use in cellular respiration or storage. Minerals are absorbed in the roots (a source) and transported to the shoots to allow cell division and growth.

  5. Cohesion-tension theory It accounts for the upward movement of water in plants. According to this theory, the elimination of a water molecule by perspiration results in a pressure below atmospheric in leaf cells, inducing the entry of another molecule of water from the vascular tissue, which, following cohesive property of water, carries with it a chain of water molecules extending from the root cell to the top of the plant.
