Cells with abundant plasmodesmatal connections are found in:
Elongation zone
Meristematic zone
Maturation zone
Root hair zone
Cells with abundant plasmodesmatal connections are found in the meristematic zone.
Assertion (A): The cell walls of meristems are thin, cellulosic with plasmodesmata connections
Reason (R): Meristems obtain biomolecules necessary for metabolism through plasmodesmata
