Hint: Dicot plants have a cambium strip between the xylem and phloem meristem cells. The primary function of cambium is to generate vascular cambium and to increase secondary growth is the secondary role.

Complete answer
From the inner side and phloem on the outer side, the vascular cambium creates xylem. Furthermore, the vascular cambium is divided into fascicular and interfascicular shifts. Fascicular changes are seen between xylem and phloem, while interfascicular changes are seen between the two vascular bundles, the main distinction between fascicular and interfascicular cambium.

Fascicular cambiumInterfascicular cambium
MeaningIt is a cambium which occurs within the stem vascular bundle.It is a cambium that occurs between the stem vascular bundle.
Type of MeristemIt tends to be both primary and secondary meristemIt tends to be a secondary meristem.
Derived fromThe Pro-meristemThe permanent tissues
OccurrenceAt both primary and secondary parts of stemOnly at secondary part of stem
FunctionGiving rise to the vascular primary and secondary componentsThe secondary vascular components are established.
SignificanceTo turn into the secondary components Fuses to shape a continuous ring of meristematic tissue with fascicular cambium




Note: Similarities between fascicular and interfascicular meristem:
i) Both are Meristematic cells
ii) They are also part of the vascular cambium,
iii) Both have cells actively dividing
iv) Both contain xylem at the middle and phloem at the stems periphery.
