-
Some vascular bundles are described as open because these
-
- are surrounded by pericycle but not endodermis
- are capable of producing secondary xylem and phloem
- possess conjunctive tissue between xylem and phloem
- are not surrounded by pericycle
Correct Option: B
Open vascular bundles means presence of cambium during secondary growth. Vascular cambium divides to form secondary xylem towards inner side while secondary phloem towards outside.
