Tunica corpus theory is connected with
root apex
root cap
shoot apex
secondary growth
Organization of stem apex into corpus and tunica is determined mainly by
planes of cell division
regions of meristematic activity
rate of cell growth
rate of shoot tip growth
For union between stock and scion in grafting which one is the first to occur ?
Formation of callus
Production of plasmodesmata
Differentiation of new vascular tissues
Regeneration of cortex and epidermis
A bicollateral vascular bundle is characterised by
phloem being sandwiched between xylem
transverse splitting of vascular bundle
longitudinal splitting of vascular bundle
xylem being sandwiched between phloem
Cork is formed from
cork cambium (phellogen)
vascular cambium
phloem
xylem
Vascular cambium produces
primary xylem and primary phloem
secondary xylem and secondary phloem
primary xylem and secondary phloem
secondary xylem and primary phloem
Pericycle of roots produces
mechanical support
lateral roots
vascular bundles
adventitious buds
