BIOXI06: ANATOMY OF FLOWERING PLANTS

334029 Statement A :
At some places, the cambium forms a narrow band of parenchyma, which passes through the primary xylem and the primary phloem in the radial directions.
Statement B :
The activity of cambium is under the control of many psychological and environmental factors.

334031 What is the fate of primary xylem in a dicot root showing extensive secondary growth?

1 It is retained in the centre of the axis
2 It gets crushed
3 May or may not get crushed
4 It gets surrounded by primary phloem
