MCQ
Read the following statements and choose option which contain wrong statement for growth.
(i) The period of growth is generally divided into three phases, namely, meristematic, elongation and maturation.
(ii) The constantly dividing cells, both at the root apex and the shoot apex, represent the meristematic phase of growth.
(iii) The cells proximal (just next, away from the tip) to the zone represent the phase of elongation.
(iv) Further away from the apex, i.e., more proximal to the phase of elongation, lies the portion of axis which is undergoing the phase of maturation.
(v) The cells in elongation phase region are rich in protoplasm, possess large conspicuous nuclei and cell walls are primary in nature.
(vi) Increased vacuolation, cell enlargement and new cell wall deposition are the characteristics of the cells in phase of meristematic region.
(vii) The cells of zone of maturation, attain their maximum size in terms of wall thickening and protoplasmic modifications.
