Phloem lie towards the pericyclet on the outerside of vascular bundle. Phloem consists of sieve tubes, companion cells, phloem parenchyma and phloem fibres. The companion cells and phloem parenchyma are connected with sieve tubes through pits. They help in lateral flow of organic food. The companion cells also control the functions of the sieve tubes. The sieve tubes conduct organic food longitudinally
