Question

Distinguish between Fascicular cambium and interfascicular cambium.

Answer 1

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 cambium| Interfascicular cambium
---|---|---
Meaning| It is a cambium which occurs within the stem vascular bundle.| It is a cambium that occurs between the stem vascular bundle.
Type of Meristem| It tends to be both primary and secondary meristem| It tends to be a secondary meristem.
Derived from| The Pro-meristem| The permanent tissues
Occurrence| At both primary and secondary parts of stem| Only at secondary part of stem
Function| Giving rise to the vascular primary and secondary components| The secondary vascular components are established.
Significance| To 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.
