What products does the vascular cambium produce?

What products does the vascular cambium produce?

Cell division by the cambium produces cells that become secondary xylem and phloem. As secondary phloem and xylem tissue accumulates, it both increases the girth of the stem and forms wood and bark.

Do vascular plants have xylem and phloem?

Vascular plants (tracheophytes) differ from the nonvascular bryophytes in that they possess specialized supporting and water-conducting tissue, called xylem, and food-conducting tissue, called phloem.

What does the cambium do?

C: The cambium cell layer is the growing part of the trunk. It annually produces new bark and new wood in response to hormones that pass down through the phloem with food from the leaves. These hormones, called “auxins”, stimulate growth in cells.

What’s the difference between Procambium and vascular cambium?

Learn about this topic in these articles: The procambium is a meristematic tissue concerned with providing the primary tissues of the vascular system; the cambium proper is the continuous cylinder of meristematic cells responsible for producing the new vascular tissues in mature stems and roots.

Where is vascular cambium found?

The vascular cambium is the main growth tissue in the stems and roots of many plants, specifically in dicots such as buttercups and oak trees, gymnosperms such as pine trees, as well as in certain other vascular plants.

Why is there more xylem than phloem?

The vascular cambium produces more xylem than phloem because the xylem progenitor cells periclinally divide more times. Interfascicular cambium differentiates from parenchyma or collenchyma cells located between the vascular bundles (mainly in stem).

Where does the secondary xylem of the cambium originate?

The vascular cambium arises between the primary xylem and phloem of a young stem or root. Parenchymatous cells become meristematic and begin to produce secondary xylem or wood toward the inside of the cambium and secondary phloem toward the outside of the cambium.

Where are the phloem and xylem located on a plant?

Phloem 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.

How does the vascular cambium differentiate from procambial cells?

In dicot stems, the vascular cambium initially differentiates from procambial cells within the vascular bundles (Fig. 1.8A ). This fascicular cambium may contribute additional cells to both the xylem and the phloem of the bundle.

How are the xylem and phloem arranged in the eudicot?

Xylem and phloem travel entire length of stems in discrete threads called ‘vascular bundles’. In eudicots, vascular bundles are arranged in a ring within the stem. Each vascular bundle is orientated with the xylem on the interior and the phloem on the outside of the xylem.
