Q12 / 180 · NEET 2019 (Odisha) · Botany

In dicot root, the vascular cambium originates from

Correct answer
A
tissue located below the phloem bundles and a portion of pericycle tissue above protoxylem
B
cortical region
C
parenchyma between endodermis and pericycle
D
intrafascicular and interfascicular tissue in a ring

Solution

In dicot root, the vascular cambium originates from tissues located below the phloem bundles and a portion of pericycle tissue above protoxylem. Vascular cambium is the meristematic layer that is responsible for cutting off vascular tissues (xylem and phloem). In young stem, it is present in patches as a single layer between the xylem and phloem.

Hence, the correct answer is option: 'A'.
