Consider the following statement:
(a) Complimentary cells are thin walled, rounded, colourless parenchymatous ad 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?

Study the given statements carefully and give the answer. (A)Bark is a nontechnical term that refers to all tissues exterior to the vascular cambium only (B)Phellem, phellogen and phelloderm are collectively called pericarp. (C)In the dicot stem vascular cambium is completely secondary in origin. (D)In dicot stem endodermis cells are rich in starch grains and the layer is also called starch sheath.

How many of the following meristems are completely secondary in origin ? A. Cork cambium of a dicot stem B. Vascular cambium of a dicot stem C. Cork cambium of a dicot root D. Vascular cambium of a dicot root

How many of the following meristems are completely secondary in origin ? A. Cork cambium of a dicot stem B. Vascular cambium of a dicot stem C. Cork cambium of a dicot root D. Vascular cambium of a dicot root

Identify the statements as true (T) or false (F) w.r.t secondary growth in root and choose the correct option. I. Vascular cambium is partially secondary in origin. II. Vascular cambium is formed as continuous and complete but wavy ring. III. Cork cambium arises from cortical cells.
