Distinguish between the following: Interfascicular cambium and intrafascicular cambium.

(N/A) The differences between intrafascicular cambium and interfascicular cambium are as follows:
$1$. Intrafascicular cambium is present within the vascular bundles,between the xylem and phloem,and is primary in origin.
$2$. Interfascicular cambium arises from the medullary rays (parenchymatous cells) located between the vascular bundles and is secondary in origin.
$3$. Both types of cambium together form a complete ring of cambium known as the vascular cambium ring,which is responsible for secondary growth in dicot stems.
