Options
- ARadial vascular bundle - Xylem and phloem on different radii
- BBicollateral vascular bundle - Phloem present on both sides of xylem
- COpen vascular bundle - Phloem surrounds xylem
- DConjoint vascular bundle - Xylem and phloem on same radii
Correct answer
C. Open vascular bundle - Phloem surrounds xylem
Step-by-step solution
Vascular bundles are components of the vascular tissue system that consist of two main parts i.e.xylem and phloem. In which xylem is called water-conducting tissue and phloem is called food conducting tissue. The vascular bundles can be of two types like radial and conjoint. Conjoint further subdivided into collateral, bicollateral, and concentric. In dicotyledonous stems, cambium is present between phloem and xylem. Such vascular bundles because of the presence of cambium possess the ability to form secondary xyle
