Xylem and Phloem Differences in Biology Import Concepts Must to Know

Question. Difference Between Xylem and Phloem.

Answer:

Table of Difference between Xylem and Phloem
Differentiating PropertyXylemPhloem
MeaningComplex tissue of plants that transports water and nutrients within the plant.Living tissue that transports food and organic materials within the plant.
Type of CellContains dead cells with the exception of parenchyma.Contains of mostly living cells.
MaterialsIt comprises of fiber, tracheid, and xylem vessels.It comprises of sieve cells, sieve tubes, phloem fibers, phloem parenchyma, and companion cells.
LocationThe location of xylem is deep in the plant, in the centre of vascular bundle.The location of phloem is on the outer side of the plant՚s vascular bundle.
Mechanical SupportIt provides mechanical support.Provides no mechanical support.
Type of MovementThese tissues move in a Unidirectional. (Only in one direction – upward direction) .These tissues move in a Bidirectional. (Both ways – up and down)
Xylem and Phloem functioningTransports only waters and minerals from roots.Transports food materials whose preparation takes place by the green parts of the plant.
Proportion of PlantXylem constitutes mostly the bulk of the body of the plant.Phloem constitutes a small part of the body of the plant.
Conducting CellsIn xylem, the conducting cells are dead.In phloem, the conducting cells are certainly living.
FibersXylem fibers are smaller.Phloem fibers are larger.
Found InThey are present in roots, stems and leaves.They are present in stems and leaves, which later transports and grow in roots, fruits and seeds.
No of TissuesThe total amount of xylem tissue is more.The total amount of phloem tissue is less.
FeaturesIt consists of tracheid, vessel elements, xylem parenchyma, xylem sclerenchyma and xylem fibres.It consists of four elements: companion cells, sieve tubes, bast fibres, phloem fibres, intermediary cells and the phloem parenchyma.
FunctionsTransports soluble mineral nutrients and water molecules from the roots to the aerial parts of the plant.

Provides mechanical strength to the plant and helps in strengthening the stem.

Transports food and other nutrients including sugar and amino acids from leaves to storage organs and growing parts of the plant.

Translocate the synthesized sugars by the photosynthetic areas of plants to storage organs like roots, bulbs and tubers.

Vascular BundlesForms vascular bundles with phloem.Forms vascular bundles with xylem.
ResponsibleIt is responsible for replacing the total amount of lost water molecules through transpiration and photosynthesis.It is responsible for transporting proteins and mRNAs throughout the plant.
