Xylem

xylem conducts water and dissolved minerals from the roots of leaves of a plant . xylem is composed of tracheids, vessel elements, xylem parenchyma ,and xylem fibres .

1. Tracheids

tracheids are long thin , dead cells that are connected together at that rapid in their cell wall contains league in which provide structure support to the xylem .

2. Vessel elements

vessel elements added to like that starch that are connected together to end to end they are wider and short then catch rights to form a long tube like structure the ends of cell contains the formation of states which have a number of holes in the cell walls .

3. Xylem parenchyma

these are the only living components of xylem tissues they conduct water and store food for a plant.

4. Xylem fibres

they are the scratch matches fibres connected with tracheids and vessels they are dead cells with thick cell wall. they provide strength to xylem tissue.

Phloem

phloem is found in all parts of plant is made up of living tubular services provide passage for downward movement of sugars , organic compounds and minerals as plant cell by the leaves to other parts of the plants.

the phloem consists of Sieve tubes , companion cells , phloem parents and phloem fibres .

1. sieve tubes

they are long thin cylinder and living cells connected to end to end and former tube like structure that conducts the food minerals throughout the plant body

2.companion cells

these cells are specialised financial asset located outside and alongside the sieve tubes and that are connected by a number of channels to the seive tubes .

Answer:

XYLEM AND PHLOEM

The xylem and the phloem make up the vascular tissue of a plant and transports water, sugars, and other important substances around a plant. What is commonly referred to as ‘sap’ is indeed the substances that are being transported around a plant by its xylem and phloem.

The separation between plants that have veins and plants that do not is one of the great divides within the plant kingdom. This separates plants into vascular and non-vascular plants. Most plants have xylem and phloem and are known as vascular plants but some more simple plants, such as mosses and algae, do not have xylem or phloem and are known as non-vascular plants.

Vascular tissue in a celery stalkPhloem and xylem are closely associated and are usually found right next to one another. One xylem and one phloem are known as a ‘vascular bundle’ and most plants have multiple vascular bundles running the length of their leaves, stems, and roots.

Xylem tissue is used mostly for transporting water from roots to stems and leaves but also transports other dissolved compounds. Phloem is responsible for transporting food produced from photosynthesis from leaves to non-photosynthesizing parts of a plant such as roots and stems.
