NEET Botany Phases of Growth MCQ Question
Which of the following statements about the phases of growth in plants is correct?
The phase of elongation is characterized by increased vacuolation and cell enlargement.
Differentiation occurs only at the shoot apex and not in root apical meristems.
Secondary growth is responsible for the elongation of plant organs.
Maturation involves the cells attaining maximal size through wall thickening and protoplasmic modifications.
Correct Answer
Detailed Explanation
The phase of elongation is indeed characterized by increased vacuolation and cell enlargement as stated in the NCERT context. Options B and C are incorrect as differentiation occurs in both apical meristems and secondary growth is responsible for increasing girth, not elongation. Option D, while partially true, does not specify that maturation occurs after elongation.
