Definitions &Translations It is one of the many layers of bark, between the cork and primary phloem. The function of cork cambium is to produce the cork, a tough protective material. Synonyms for cork cambium are bark cambium, pericambium and phellogen. Phellogen is defined as the meristematic cell layer responsible for the development of the periderm.

- Bark comprises all the tissues outside the vascular cambium of a vascular plant. The majority of the bark of woody plants develops from three meristems: the vascular cambium that gives rise to the secondary phloem, the phellogen that gives rise to the cork and dilatation meristem that produces parenchyma cells to avoid cracking when the axis increases in diameter.

xylem xylem. n. 1. (Botany) a plant tissue that conducts water and mineral salts from the roots to all other parts, provides mechanical support, and forms the wood of trees and shrubs. It is of two types (protoxylem and metaxylem), both of which are made up mainly of vessels and tracheids.zī′ləm). xylem. Xylem cells in the stem carry water from a plant's roots to its leaves. The phloem distributes food that is made in the plant's leaves to other parts of the plant. The cambium cells divide into either xylem or phloem cells.

Meristems Two cell types occur within the cambium: 1  Fusiform initials. They are the mother cells of all xylem and phloem elements, as well as of all other cells that are oriented parallel to the organ's axis. 2  Ray initials are nearly isodiametric, small cells that occur often in groups. They develop from fusiform initials or their progenitors.

Difference Between Vascular Cambium and Cork Cambium The cork cambium, cork, and phelloderm collectively known as the periderm. In the periderm, there are small, raised areas called lenticels. These areas consist of more spaces between cork cells, which enable gas exchange between inner live cells of woody stem or root with the outside air.

xylem (zī'ləm) A tissue in vascular plants that carries water and dissolved minerals from the roots and provides support for softer tissues. Xylem consists of several different types of cells: fibers for support, parenchyma for storage, and tracheary elements for the transport of water. The tracheary elements are arranged as long tubes through which columns of water are raised. In a tree trunk, the innermost part of the wood is dead but structurally strong xylem, while the outer part consists of living xylem, and beyond it, layers of cambium and phloem.

Gorilla Between the species, and even within the species, gorillas live in a variety of habitats and elevations. Gorilla habitat ranges from montane forests to swamps. Eastern gorillas inhabit montane and submontane forests between 650 and 4,000 m (2,130 and 13,120 ft) above sea level.

Cork cambium Cork cambium (pl. cambia or cambiums) is a tissue found in many vascular plants as part of the periderm. The cork cambium is a lateral meristem and is responsible for secondary growth that replaces the epidermis in roots and stems.It is found in woody and many herbaceous dicots, gymnosperms and some monocots (although monocots usually lack secondary growth).t is one of the many layers of bark, between the cork and primary phloem. The function of cork cambium is to produce the cork, a tough protective material. Synonyms for cork cambium are bark cambium, pericambium and phellogen.

Periosteum connsists of … dense irregular connective tissue. Periosteum is divided into an outer fibrous layer and inner cambium layer (or osteogenic layer).The fibrous layer contains fibroblasts, while the cambium layer contains progenitor cells that develop into osteoblasts.

The periosteum isolates the bound surrounding the tissue, provides a route for the circu … latory and nervous supply and actively particiapates in bone growth and repair.

cambium The cambium is in the shape of a monostichous concentric cylinder (in cross section, it appears annular). As a result of cambial activity, the axial organs grow in thickness. Secondary phloem is produced toward the outside of the axis, and secondary xylem toward the inside.
