In a dicot stem cross section, medullary rays are
ARadial rows of parenchyma between bundles
BLignified tissues forming the central pith
CLayers of collenchyma in hypodermis
DEndodermal cells with Casparian strips
Answer & Solution
Correct answer: A. Radial rows of parenchyma between bundles
Medullary rays are radially placed parenchymatous cells between adjacent vascular bundles. They store and translocate. During secondary growth, they extend through the vascular cambium and contribute to secondary xylem rays.
