Which of the following statements regarding the different phases of plant growth is correct?
Options
- ACells in the zone of elongation are characterized by a rich protoplasm and large conspicuous nuclei.
- BThe zone of maturation lies distal to the zone of elongation in a growing root apex.
- CCells in the meristematic phase possess primary, thin, and cellulosic cell walls with abundant plasmodesmatal
- DThe cells in the elongation phase attain their maximal size in terms of wall thickening and protoplasmic modif
Correct answer
C. Cells in the meristematic phase possess primary, thin, and cellulosic cell walls with abundant plasmodesmatal
Step-by-step solution
The period of growth is generally divided into three phases: meristematic, elongation, and maturation. The constantly dividing cells, both at the root apex and the shoot apex, represent the meristematic phase of growth. The cells in this region are rich in protoplasm, possess large conspicuous nuclei, and their cell walls are primary in nature, thin, and cellulosic with abundant plasmodesmatal connections. The cells proximal (just next, away from the tip) to the meristematic zone represent the phase of elongation.
