no there is no cambium present in monocot roots.
Vascular cambium is responsible for secondary growth in a stem.
woody stems have more xylem than soft stems
The function of vascular cambium in dicots is to give rise to new vascular tissue.
The primary growth in vascular plants takes place with the differentiation of vascular tissue from parenchymatous cells and the secondary growth takes place when the intra-vascular and inter vascular cambium adds to the secondary phloem and secondary xylem.
It increases the girth of the stem......................
Simply put, these are the growth areas of the plant.
secondary xylem
The cambium is the layer of actively dividing cells between the xylem and phloem tissues of plants. It is responsible for the secondary growth of plants.
It gives rise to the vascular tissues of phloem and xylem. Thus it helps in the secondary growth of a plant.
Lateral meristems. Usually, vascular tissue is produced in the center of the stalk and grows outward continually. The vascular cambium is responsible for the new vascular tissue and the cork cambium produces new dermal coverings.
Secondary growth is important because as larger plants grow, more vascular tissue (responsible for transport of water, sugar and minerals) is needed to keep up with the constant growing of the plant. Limit the vascular tissue and the plant will have insufficient amount of water and sugar conduit for transportation throughout.
