Translocation is the transport of nutrients and solutes throughout the plant. This is done by the phloem which carries food and minerals throughout the plant. Phloem, unlike xylem, transports materials (carbohydrates) both upwards and downwards which act as food for the plant. They are composed of sieve tubes and companion cells. The companion cells conduct sugars into the sieve tubes which transport the sugar through the phloem.
