When xylem and phloem are separated by a strip of cambium vascular bundle is called
A
collateral and open
B
collateral and closed
C
bicollateral and open
D
concentric and closed
Explanation: 

Detailed explanation-1: -Presence of cambium possess the ability to form secondary xylem and phloem tissues, and hence are called open vascular bundles. If the xylem and phloem are situated on the same radius of vascular bundles, then they are called conjoint and collateral type of vascular bundles.

Detailed explanation-2: -The cambium is found to be present in between the xylem and phloem, such bundles are called open vascular bundle. When the cambium is absent in between the xylem and phloem, such bundles are called close vascular bundle. In the Dicotyledonous stem, each vascular bundle is conjoint, open, collateral, and bi-collateral.

Detailed explanation-3: -Final Answer: The dividing tissue present between xylem and phloem of the stem in the plants is Vascular cambium.

Detailed explanation-4: -The cambium which is located within the vascular bundles, that is between the primary phloem and primary xylem is called the intrafascicular cambium.
