Select incorrect statement :- A Vascular cambium and cork cambium are example of lateral meristems B B In dicot stems, endodermis is also referred as starch sheath С Bark is a technical term D Vascular cambium is completely secondary in origin in dicotyledonae roots

Vascular cambium of dicot root is purely secondary in origin and airse from

Assertion: Fascicular vascular cambium, interfascicular cambium and cork-cambium are examples of lateral meristems. Reason: These are responsible for producing the secondary tissues.

Assertion :- Both vascular cambium and cork cambium are lateral meristem. Reason :- Both are involved in secondary growth of plant by additon of cells in lateral direction of main axis.

Lateral roots and vascular cambium originates due to the activity of which tissue in dicot root ?

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?

Identify the correct pair of statemetns. I. Functions of sieve tubes are controlled by the nucleus of companion cells. II. Albuminous cells are present in angiosperms. III. In dicot root, the vascular cambium is completely secondary in origin. IV. Cylindrical meristems contribute to the formation of primary plant body.

Select the incorrect statement/s : (A) Root apical meristem and shoot apical meristem are responsible for the secondary growth of the plants (B) Root apical meristem and shoot apical meristem contribute to increasing girth of the plant organs (C) In dicotyledonous plants and gymnosperms the lateral meristems, vascular cambium and cork cambium contribute to the elongation of the plant organs in which they are active (D) The development is the sum of growth and differentiation

(a.) In the young dicot stem, cambium present in patches as a single layer between xylem and y. (b.) Vascular and cork cambium both are form the lateral meristem. (C.) The medullary cells are derived from the interfascicluar cambium. In given statements, which of the following are correct ?

(i) Cork cambium is an example of lateral meristem . (ii) In the young dicot stem. Cambium present in patches as a single layer between xylem and phloem. (iii) Interfascicular cambium and Interfascicular cambium combinedly from cambial ring. In given Statements, which of the following are correct ?
