Phloem and xylem are complicated tissues that perform transportation of food and also water in a plant. They room the vascular organization of the plant and also together type vascular bundles. They occupational together together a unit come bring around effective transport of food, nutrients, minerals and also water.

Transportation that food and nutrients such as sugar and amino acids from pipeline to storage organs and also growing components of plant. This movement of building material is referred to as translocation.

You are watching: How do the cells of the xylem compare to the cells of the phloem?

Water and mineral transfer from roots to aerial components of the plant.
Bidirectional (Moves up or under the plant"s stem native "source to sink") Unidirectional (Moves increase the plant"s stem)
Roots, stems and leaves. Transports sucrose to expansion (roots and shoots) and storage areas of the tree (seeds fruit and also swollen roots) Roots, stems and also leaves
Forms vascular bundles through xylem Forms vascular bundles through phloem and also gives mechanical stamin to plant because of presence of lignin cells. The lignified second wall additionally makes the xylem waterproof and also prevent it from collapsing under the press of water transpiration
Elongated, tubular shape with slim walled sieve tubes. The sieve tubes have pores at each end in the overcome walls and also microtubules the extend between sieve elements permitting longitudinal circulation of material. Tubular shape with no cross walls which allows a continuous column the water + facilitates an ext rapid carry within the xylem vessels. There room two varieties - protoxylem (first created xylem) + metaxylem (mature xylem) depending upon pattern the lignin.
Sieve tubes, companion cells, phloem parenchyma (loosely packed resulting in intercellular spaces which allows gas exchange), bast fibers, intermediary cells, Tracheids, courage elements, xylem parenchyma (loosely packed resulting in intercellular spaces which allows gas exchange), xylem sclerenchyma
Living tissue with small cytoplasm yet no nucleus/tonoplast. Dead organization at maturity so it is hollow with no cabinet contents
Phloem is no star shaped. Xylem is star shaped.
Phloem occur on outer side that the vascular bundle. Xylem occupies the center of the vascular bundle.


Xylem is created by tracheary aspects like tracheids and vessels predominantly. There are a range of various other cells giving it the standing of complicated tissue. Major xylem originates native the procambium throughout primary development while secondary xylem has actually its beginning in vascular cambium during an additional growth.


Phloem has actually sieve tubes, companion cells, bast fibers as its elements. Phloem originates from meristematic cell in vascular cambium- primary phloem indigenous apical meristem and secondary phloem native vascular cambium.


Sap components

Xylem sap has water, not natural ions and also a couple of organic chemicals. Phloem sap contains water and also sugars.



Both phloem and xylem room tubular structures that facilitate easy transportation. In xylem vessels water travels by mass flow rather than cell diffusion. In phloem, concentration of necessary substance within a phloem cabinet (e.g., leaf) create a diffusion gradient by which water flows right into cells and phloem sap move from source of organic problem to sugar sinks through turgor pressure.

Negative pressure facilitates motion of water and also minerals in xylem if in phloem optimistic hydrostatic pressures room responsible because that transportation. Therefore phloem loading and also unloading brings about translocation.

Functions the Xylem and also Phloem

Xylem transports water and also soluble mineral nutrients from roots to various parts of the plant. It is responsible because that replacing water shed through transpiration and photosynthesis. Phloem translocates street made by photosynthetic locations of plants to storage organs favor roots, tubers or bulbs.

This video clip explains the organic makeup of xylem and phloem and their function in plant transport.


A plant can be eliminated by stripping far the bark in a circle around the tribe or stem. This destroys the phloem, i beg your pardon is current towards the outside of xylem. This is calle girdling, however such a procedure has no impact on xylem. This technique is used to create oversized fruits and vegetables.
