what is the difference between xylem and pholem?

\huge\boxed{\fcolorbox{pink}{silver}{AnsWer}}

Differences:-

  1. Xylem is the complex tissue of plants, responsible for transporting water and other soluble nutrients to the plants and the flow is unidirectional which is from root to the upper part of the plant, while on the other hand phloem is the another kind of the vascular, living tissue which is responsible for transporting food and other organic materials, prepared by the green parts of the plants like leaves. The flow of material in phloem is bi-directional.
  2. Xylem mainly made up of dead cells and parenchyma is the only living cells present, whereas phloem mainly contains living cells and fibers are the only dead cells.
  3. Xylem is found in the center of the vascular bundle, deep in the plant and made up of xylem vessels, fiber, and tracheids, whereas phloem is found on the outer side of the vascular bundle and made up of phloem fibers, sieve tubes, sieve cells, phloem parenchyma and companion cells.
  4. Xylem transports only minerals and waters from the roots, and also provide mechanical strength to the plant, on the contrary phloem transports food materials that are prepared by the green parts of the plants to other parts but is incapable of providing mechanical support to the plant.
  5. Xylem often constitutes the bulk of the plant body, but the conducting cells or tracheary cells are dead, while phloem forms a small part of the plant body and the conducting cells are living.

I hope this helps you...

Answer:

Xylem

1- it contains only 1 living tissue and 4 dead

2- it's main conducting elements are trachieds and vessels.

3- it is also known as wood

4- it conducts water and minerals.

5- it does unidirectional conduction.

Phloem

1- it contains 4 living and one dead tissue.

2- it's main conducting elements are seive tubes.

3- it is also known as bast.

4- it conducts food.

5- it does bidirectional conduction

hope this helps
