presence of p-protein
enucleate condition
thick secondary walls
The apical meristem of the root is present
in all the roots
only in radicals
only in tap roots
only in adventitious roots
Vascular tissue in flowering plants develop from
phellogen
plerome
eriblem
dermatogen
Vascular cambium produces
primary xylem and primary phloem
secondary xylem and secondary phloem
primary xylem and secondary phloem
secondary xylem and primary phloem
