Both xylem and phloem have cellulose; Both tissues contain chloroplast; Both have … Thus, it forms cones and strobilus. Drought limits the long-distance transport of water in the xylem due to the reduced leaf-to-soil water potential difference and possible embolism-related losses of conductance and of sugars in the phloem due to the higher viscosity of the dehydrated sugary solution. Let us explore the major differences between xylem and phloem in detail. Mainly contains living cells (fibers are the only dead cells in the phloem). Amount of phloem is less than that of xylem. Seasonal wood and phloem development was monitored during the growing seasons of 2011 and 2012 by taking small punched cores from eight trees/species of the outermost tree rings (micro-cores) with a diameter and length of 2.5 mm and c. 2 cm, respectively (Rossi et al. Consists of mainly dead cells (only parenchyma is the living cells in the xylem). The rate of flow in the xylem is controlled by external factors via the stomata (e.g. Xylem is present in the center of the vascular bundles, deep in the plant and made up of xylem vessels, fiber and tracheids whereas phloem is located on the outer side of the vascular bundles and made up of phloem fibers, sieve tubes, sieve cells, phloem parenchyma and companion cells. Amount of xylem is more than that of phloem. ADVERTISEMENTS: 3. What’s more, it has fibrous roots. Dicot plants have both cork and vascular cambium. 2.
