A plant's cambium is the layer of cells lying between the wood and bark of a stem from which new bark and wood cells originate. Be careful when engaging tree services that their climbing spikes do not damage the cambium cells.

A layer of growing cells with stems and roots of vascular plants that gives rise to phloem and xylem.
a layer of actively dividing cells (lateral meristem), found within stems and roots, that gives rise to secondary growth in perennial plants, causing an increase in girth. There are two main types of cambium: vascular cambium, which gives rise to secondary xylem and phloem tissues, and cork cambium (or phellogen), which gives rise to secondary cortex and cork tissues, as in bark. Image from the Population Biology site of San Diego State University. The vascular cambium surrounds the roots, trunk, branches, and shoots, extending throughout a tree. Each year, the vascular cambium produces a new layer of phloem toward the outside of the tree and a new layer of xylem, or wood, toward the inside.

A layer of living cells in a woody plant, such as a tree, between the bark and the wood of the stem. The cambium produces phloem (to the outside) and xylem (to the inside). In dicot woody plants, the xylem makes up what we call the tree's rings.

layer of lateral meristematic cells; produces phloem and xylem tissue.
meristematic tissue in woody plants that lies between the bark and wood; usually only one or two cells thick; divides into the cells that gives a woody plant thickness (or caliper).
The layer just inside a tree's bar...
The layer of living tissue [typically green] between the sapwood and the bark. In regions where there are alternating seasons, each year's growth laid down by the cambium is discernible because of the contrast between the large wood elements produced in the spring and the smaller ones produced in the summer. These are the annual rings, by which the age of a tree can be established.
A single layer of cells between the woody part of the tree and the bark. Division of these cells result in diameter growth of the tree through formation of wood cells (xylem) and inner bark (phloem).
the thin layer of living cells just under the bark that produces wood and bark
Layer or zone of dividing cells that produce xylem in the inner portions of the plant, and phloem in the outer portions of the plant. Also called vascular cambium.
(Vascular Cambium) The actively dividing layer of cells that lies between the bark and the sapwood and gives rise to secondary xylem and phloem or, in other words, the layer of tissue just beneath the bark from which the new wood and bark cells of each year's growth develop (the growing part of a tree).
A lateral meristem in plants. Types of cambiums include vascular, cork, and intercalary.
The layer of cells between the inner bark and wood tree. This is where growth takes place. The cambium forms sapwood (xylem) to the inside and bark (phloem) to the outside.
is a thin layer of meristematic cells located between the bark (periderm, cortex and phloem) and the wood (xylem). Its cells are in continues division originating new cells. For a successful graft union, its really important that the cambium of the scion be in close contact with the cambium of the rootstock.
Formative one-cell-thick layer of tissue between xylem (woody tissue) and phloem (bark) in most vascular plants that is responsible for secondary growth.
a persistent layer of generative, meristematic cells that gives rise to secondary wood (xylem) and secondary inner bark (phloem).
The layer of cells on a tree stem that form the boundary between bark and wood. Leaves, pith and cambium are the only growing part of the stem.
layer which forms across and between primary bundles where each year cells in this layer divide and grow. As the cambium divides, wood and bark cells form.

the layer of cells that lies between, and gives rise by active division to, secondary xylem and secondary phloem, i.e., to wood and the innermost living bark.
A layer, one- or two-celled thick, between the xylem and phloem in higher plants. The cambium produces both of these tissues, resulting in diameter growth.
A thin layer of tissue between the bark and the wood in a tree which repeatedly subdivides to form new wood and bark cells.

a lateral meristem that produces secondary growth
The live, actively growing, layer of a tree. The cambium is one cell thick and resides between the sapwood and the phloem. It repeatedly divides itself to form new wood and causes the tree to grow and expand.
( kàm´-bê-em) - A layer of growing tissue the seperates the xylem and phloem and continuously produces new xylem and phloem cells.
Layer of actively dividing cells between the xylem (sapwood) and the phloem (inner bark)of trees, which forms additional conducting tissue, therefore increasing the girth of a stem, branch, or trunk.
Layer of actively dividing cells between the bark and the wood. Chlorophyll: The green photosynthetic pigment found in plants, algae, and cyanobacteria. Its name is derived from ancient Greek; chloros = green and phyllon = leaf. Chlorophyll absorbs mostly in the blue and to a lesser extent red portions of the electromagnetic spectrum, thus its intense green color. Chlorosis: An unhealthy condition shown by yellowing of foliage or shoot tips. Occurs when chlorophyll is destroyed or its formation is inhibited by nutrient deficiencies, drought, disease or other environmental factors.

Group of cells, which divide to form new xylem and phloem cells.
Layer of living cells just under bark and at growing tips of shoots and roots, from which new growth develops.
