Phloem cell facts
WebbPHLOEM – translocation of food made by the leaves to the other parts of the plant. COMPOSED OF: COMPANION CELLS – small, nucleated parenchymatous cells that are usually associated with some sieve tubes. PHLOEM FIBERS – look like ordinary sclerenchyma fibers. WebbFood is transported in plants by a special organ called the phloem. Phloem transports food materials from leaves to different parts of a plant. Transportation of food in phloem is achieved by the expenditure of energy from ATP. This increases osmotic pressure in the tissue, causing water to move. This pressure moves material in the Phloem to the
