fascicular cambium
The cambium present between the xylem and phloem of vascular bundle is called vascular cambium. It is a lateral meristem that gives rise to secondary xylem and phloem and occurs in the form of a thin strip. Vascular cambium is also called fascicular cambium.

The transverse section of a plant material shows the following anatomical features:
(a) the vascular bundles are conjoint, scattered and surrounded by a sclerenchymatous bundle sheaths.
(b) phloem parenchyma is absent. What will you identify it as?

Cork cambium forms tissues that form the cork. Do you agree with this statement? Explain.
A transverse section of stem is stained first with safranin and then with fast green following the usual schedule of double staining for the preparation of a permanent slide. What would be the colour of the stained xylem and phloem?
