Consider the following statement: (a) Complimentary cells are thin walled, rounded, colourless parenchymatous and non-suberized (b) secondary phloem and periderm are included in bark. (c) In a dicot root, vascular combium is completely secondary in origin (d) In a dicot root, vascular cambium is initially wavy which later becomes circular. How many of above statemetns are correct?
