In plants that bring the food made of leaves to all the other areas of the plant, Phloem is also known as bast. Phloem is made of different cells, called sieve channels, phloem fibers, complementary cells and parenchymatic phloem cells. Primary phloem consists of the epidermal cells of root and shoot tips (zones of new cell production), either of the propellant, the cells of which ripen before elongation, or the metaphloem in which the cells mature after elongation, during development.
