The ends of the roots and shoots grow. It increases the girth of older tissues. Conducts water and minerals from the soil to other parts of the plant. At maturity these cells are dead. These tissues are made of long cells on top of one another with holes between the cells.
Cell walls have lots of cellulose and lignin.
Conducts sugar and other solutes to other parts of the plant. At maturity cells are alive, but often have no nuclei. Covers the plant Above ground, waxes and cutin cover leaves and stem to restrict water loss and retard microbial attack. This non-cellular cover is called the cuticle. Cell walls secrete suberin, a waxy substance that waterproofs.
