The vascular cambium is a lateral meristem: The vascular cambium is the source of both the secondary xylem (inwards, towards the pith) and the secondary phloem (outwards), and is located between these tissues in the stem and root. A meristem is a tissue in all Plants consisting of undifferentiated cells ( meristematic cells) and found in zones of the plant where growth can take place In Vascular plants xylem is one of the two types of transport tissue Phloem being the other In Vascular plants phloem is the living tissue that carries organic Nutrients (known as photosynthate particularly Sucrose, a sugar to A few leaves even have a vascular cambium. [2]
The vascular cambium usually consist of two types of cells:
- Fusiform initials (tall cells, axially-oriented)
- Ray initials (almost isodiametric cells - smaller and round to angular in shape)
Vascular cambium is a type of meristem - a tissue consisting of embryonic (incompletely differentiated) cells from which other (and more differentiated) plant tissues originate. A meristem is a tissue in all Plants consisting of undifferentiated cells ( meristematic cells) and found in zones of the plant where growth can take place The cell is the structural and functional unit of all known living Organisms It is the smallest unit of an organism that is classified as living and is often called Primary meristems are the apical meristems on root tips and shoot tips. A meristem is a tissue in all Plants consisting of undifferentiated cells ( meristematic cells) and found in zones of the plant where growth can take place Another lateral meristem is the cork cambium, which produces cork, part of the bark. Cork cambium is a tissue found in many vascular plants as part of the Periderm.
Vascular cambia are found in dicots and gymnosperms but not monocots, which usually lack secondary growth. Dicotyledons, or "dicots", is a name for a group of Flowering plants whose Seed typically has two embryonic leaves or Cotyledons There Gymnosperm (Gymnospermae are a group of Spermatophyte seed-bearing Plants with Ovules on the edge or blade of an open Sporophyll, which are Monocotyledons or monocots are one of two major groups of Flowering plants (angiosperms that are traditionally recognised the other being Dicotyledons
For successful grafting, the vascular cambia of the stock and scion must be aligned so they can grow together. Grafting is a method of asexual Plant propagation widely used in Agriculture and Horticulture where the tissues of one Plant are encouraged to
