In pretty much all plants, the cabium is that green skin just under the bark (if the plant has an outer bark) and it carries most of the nutrients etc from the roots up and the oxygen etc from the leaves down.

Cambium is a tree layer between the bark and the heart of the tree trunk. It is a living part of the tree, and is partially responsible for healing any gashes in the trunk and also for transporting materials through the tree.
Trees have two types of growth: primary growth and secondary growth. · Primary growth occurs at the tips of roots and stems and results in their growing taller or longer. · Secondary growth takes place in the vascular cambium and the cork cambium and results in an increase in the diameter of the stem or trunk of the tree. Cambium lies between the old wood and the bark of the tree. The vascular cambium is a thin layer cells that produces conducting cells - xylem and phloem. · The phloem is the outer layer, and is sometimes referred to as the inner bark. It is a food conducting tissue. The xylem is located toward the inside of the cambium layer. · The xylem is the vascular tissue through which most of the water and minerals of the tree are conducted. More secondary xylem (added toward the inside of the cambium layer) than secondary phloem (added toward the outside of the cambium layer) is produced by the cambium. The definition of wood is secondary xylem, reflected by the origin of the term 'xylem', the Greek word xylon, for wood. Another layer, the cork cambium, contributes to the expanding girth of a tree. The cork cambium is a thin layer cells that ultimately produces the bark of the tree. The bark is composed of several types of tissue produced (both toward the inside and the outside of the tree) by the cork cambium layer.
All trees have a layer of soft tissue under their bark called cambium. This layer of tissue is the path for nutrients and water to move from the ground to the very tips of the trees branches. Cutting a hole through the tree disturbs only a portion of the cambium. The part of tree/bark/cambium that was untouched remains the route for the nutrients and water to the rest of the tree.Girdling a tree is to horizontally cut through the bark and cambium around the circumference of the tree. This cuts off the supply of nutrients and water to any point above that cut. Past layers of the cambium turn into wood (the rings of a tree). The interior of a tree being past of dead cambium (the wood of the tree) is now structural and carries no water and nutrients.
Basically, you need the cambium layers to touch and grow a callous.
Roots, bark, phloem, cambium, xylem, and leaves.
From outside to inside, the botanical basics of a tree are Outer Bark, Inner Bark, Cambium, Sapwood, and Heartwood.
The trees cambium is then exposed and the tree is more prone to disease. It will grow back though.
vascular cambium
yes it does the pourpose of the cambium is to thicken the plant . I'm not sure if im right, but i think your wrong. Only woody plants have a vascular cambuim. One of the most common woody plant is a tree. If you are talking about a vascular cambium inside a tree, then no, the vascular cambuim does not expand the stem. What it does is make a second layer of bark for the tree in the comming spring.
While there is no set number, the cambium is usually a couple cells to a few (4 or 6 or so) Its location is between the sapwood of the wood part (xylem) and the inner bark layer (phloem). The cambium consists of specialized cells called "initials" which produce xylem cells to the inside or phloem cells to the outside. Since the bark of a tree is thinner than the wood, the cambium produces more xylem cells.
Bark is inactive in a tree but is constantly replaced by the active growth of the vascular cambium- which is just below the bark. Bark is basically a tree's skin on its branches and trunk.Just like damage to skin however, damage to bark (by mowers, scratching, pests, disease) can be very bad for the tree as damage to the vascular cambium could happen.
