What is the difference between fascicular and interfascicular cambium?
Dicot plants have a cambium strip between the meristem cells of the xylem and phloem. The primary role of cambium is to produce vascular cambium and the secondary role is to enhance secondary growth.
The vascular cambium produces xylem from the inner side and phloem on the outer side. The vascular cambium is further divided into fascicular and interfascicular cambium.
The core difference between fascicular and interfascicular cambium is that fascicular cambiums are found between xylem and phloem while interfascicular is found between the two vascular bundles.
What Is Fascicular Cambium?
Fascicular cambium is the meristem cells found between the xylem and phloem of the vascular bundle. It is also known as intrafascicular cambium and it develops from the procambium of the stem apex.
The main function of the fascicular cambium is to produce a xylem on the center and phloem on the outer side. The tissue is further transformed into a secondary meristem during secondary growth.
What Is Interfascicular Cambium?
Interfascicular cambium is the secondary meristem tissues occur between the two vascular bundles in the dicot stem. The cells develop from the medullary rays during secondary growth.
The main function is to form secondary xylem towards the center and secondary phloem towards the periphery of the stem.
Comparison Chart: Fascicular Cambium Vs Interfascicular Cambium
|Basic Terms||Fascicular Cambium||Interfascicular Cambium|
|Meaning||It is a cambium that occurs within the vascular bundle of the stem||It is a cambium arising between the vascular bundle of the stem|
|Type of Meristem||Tend to be both primary and secondary meristem||Tend to be secondary meristem|
|Derived from||The pro-meristem||The permanent tissues|
|Occurrence||Both primary and secondary parts of the stem||Only within the secondary parts of the stem|
|Function||Give rise to primary and secondary vascular components||Give rise to the secondary vascular components.|
|Significance||To transform into the secondary parts||Fuses with fascicular cambium to form a continuous ring of meristematic tissue|
Core Difference between Interfascicular and Fascicular Cambium In Point Form
- Fascicular cambium is found between the xylem and phloem of the vascular bundle while interfascicular cambium is present between the vascular bundles
- Fascicular cambium is the primary meristem while interfascicular cambium is the secondary meristem
- Fascicular cambium is derived from pro-meristem while interfascicular cambium is derived from the permanent tissue
- Fascicular cambium is present in the primary and secondary parts of the stem while interfascicular cambium in the secondary part of the plant
- Fascicular cambium can produce both primary and secondary component parts while interfascicular cambium produces secondary vascular tissues
- Fascicular cambium developed from the procambium of the stem apex while interfascicular cambium develops from the medullary rays during secondary growth.
Similarities between Fascicular and Interfascicular Cambium
- Both are meristematic cells
- Both are part of the vascular cambium
- Both have actively dividing cells
- Both produce xylem towards the center and phloem on the periphery of the stem
