Correct answer
D. A-2, B-3, C-1
Step-by-step solution
The period of growth is divided into three phases: meristematic, elongation, and maturation. Meristematic phase (A) cells are rich in protoplasm, possess large conspicuous nuclei, and have thin primary cellulosic cell walls with abundant plasmodesmatal connections (2). Elongation phase (B) cells are characterised by increased vacuolation (3), cell enlargement, and new cell wall deposition. Maturation phase (C) cells attain their maximal size in terms of wall thickening (1) and protoplasmic modifications. Dedifferen
