Sugars are moved about the plant in a layer of cells called the phloem. Phloem is made up of living cells located just outside the cambium. The cambium produces the phloem in trunks, branches, and roots. The tree usually expends energy moving sugars, growth regulators, proteins, and essential elements up and down the phloem to other locations in the plant. Once sugar arrives at a location, it is used to carry out normal processes or it is stored. It is stored as starch in the network of living cell contents in the xylem called the symplast.
