What is Cambium?
Definition: The cambium is an actively dividing, thin layer of cells that grows between the xylem and phloem cells. Found in woody plants and some herbaceous plants. The cambium layer is a meristem, meaning that it is a region of actively dividing cells. Cells divide, producing two new cells: an inner xylem cell and an outer phloem cell. The cambium layer thickens the stem of a plant by producing more xylem and phloem cells. Cells of cambium are living cells. They have a nucleus and organelles.
The cambium cells divide by mitosis. The cambium cells divide to produce xylem cells and phloem cells.
Classification of Vascular Bundles
There are three types of vascular bundles:
Closed vascular bundles – These are bundles of vascular tissue that are completely enclosed by a layer of connective tissue.
Open vascular bundles – These are bundles of vascular tissue that not enclosed by a layer of connective tissue.
Racemose vascular bundles – These are bundles of vascular tissue in which the individual vessels not arranged in a linear fashion.
Secondary Growth
The secondary growth in a plant is the growth that takes place after the primary growth, which is the growth of the plant during its immature phase. The secondary growth is responsible for the increase in the size of the plant, and it occurs due to the activity of the cambium, a layer of cells that is present between the bark and the wood. The cambium produces new cells on the inside of the bark and the outside of the wood, and these new cells lead to the growth of the plant.
Cork Cambium
The cork cambium is a layer of actively dividing cells located just beneath the cork bark of a tree. The cork cambium is also responsible for the growth of new tree branches and for the production of new cork tissue to seal tree wounds.
Cambium :- Have a Glance
A cambium is a thin layer of actively dividing cells between the bark and the wood of a tree. This layer is responsible for the tree’s ability to grow in diameter. The cambium produces new cells that are added to the outside of the tree (the bark) and to the inside of the tree (the wood).
