Phloem and xylem are complex tissues that perform transportation of food and water in a plant. They are the vascular tissues of the plant and together form vascular bundles. They work together as a unit to bring about effective transportation of food, nutrients, minerals and water. Show
Comparison chartPhloem versus Xylem comparison chart
AnatomyXylem is formed by tracheary elements like tracheids and vessels predominantly. There are a variety of other cells giving it the status of complex tissue. Primary xylem originates from the procambium during primary growth while secondary xylem has its origin in vascular cambium during secondary growth. Structure of xylem cells Phloem has sieve tubes, companion cells, bast fibers as its elements. Phloem originates from meristematic cells in vascular cambium- primary phloem from apical meristem and secondary phloem from vascular cambium. Structure of phloem cells Sap componentsXylem sap contains water, inorganic ions and a few organic chemicals. Phloem sap contains water and sugars. Differences between Xylem and Phloem vessels TransportationBoth phloem and xylem are tubular structures that facilitate easy transportation. In xylem vessels water travels by bulk flow rather than cell diffusion. In phloem, concentration of organic substance inside a phloem cell (e.g., leaf) creates a diffusion gradient by which water flows into cells and phloem sap moves from source of organic substance to sugar sinks by turgor pressure. Negative pressure facilitates movement of water and minerals in xylem while in phloem positive hydrostatic pressures are responsible for transportation. Hence phloem loading and unloading brings about translocation. Functions of Xylem and PhloemXylem transports water and soluble mineral nutrients from roots to various parts of the plant. It is responsible for replacing water lost through transpiration and photosynthesis. Phloem translocates sugars made by photosynthetic areas of plants to storage organs like roots, tubers or bulbs. This video explains the biological makeup of xylem and phloem and their role in plant transport. GirdlingA plant can be killed by stripping away the bark in a circle around the trunk or stem. This destroys the phloem, which is present towards the outside of xylem. This is calle girdling, but such a process has no effect on xylem. This method is used to produce oversized fruits and vegetables. Types of plant cellsThis picture presents the various types of plant cells, including xylem, phloem, sclerenchyma and collenchyma.

this comparison: If you read this far, you should follow us: "Phloem vs Xylem." Diffen.com. Diffen LLC, n.d. Web. 23 Oct 2022. < > What is the difference between xylem and phloem transport?Xylem transports water and mineral salts from the roots up to other parts of the plant, while phloem transports sucrose and amino acids between the leaves and other parts of the plant.
Which of the following is a correct statement about a difference between xylem and phloem?Correct answer:
Phloem is located in the bark of trees and transports sugars (such as sucrose) and organic compounds to the rest of the plant from the leaves. The other plant vascular tissue is xylem. Xylem is located outer wood of trees, and transports water from the roots to the leaves of trees.
Which of the following is a correct statement about a difference between xylem and phloem transport view available hint S?Xylem consists of tracheids, vessels, parenchyma, and fibers. Phloem consists of sieve tubes, companion cells, parenchyma, fibers. So, the correct answer is 'Xylem transports water and minerals absorbed by roots whereas phloem transports food prepared by leaves. '
