The main functions of tree cells are to transport water and minerals up the tree and energy-rich sap down the tree, provide strength to the tree, and store food. Hardwood cell structures contain three main cell types - vessels that transport water and minerals, fibers that provide strength, and parenchyma cells that surround vessels and store food. Softwood cell structures contain two main cell types, tracheids that provide strength and assist in water transportation through pits in their cell walls, and parenchyma cells that store food.
