Vascular cambium of stem is _______________.
In vascular plants, the secondary growth occurs due to the activity of the two lateral meristems- the cork cambium and the vascular cambium.
In woody plants, the secondary growth produces wood and gives shapes to the plant with a thickened trunk.
The vascular cambium is also known as fascicular cambium which develops within the vascular bundles that produce xylem to the inner side and phloem to the outer side.
The vascular cambium is responsible for only secondary growth.
So, the correct answer is 'Secondary meristem'.
The correct option is C.
