NEET Botany Phases of Growth MCQ Question
Which of the following statements about the phases of growth in plants is correct?
Primary growth occurs due to the activity of apical meristems and leads to elongation.
Secondary growth is initiated by the primary meristems and increases the height of the plant.
Differentiation is the process where meristematic cells divide continuously to form new cells.
Heterophylly is a result of genetic factors and does not show any environmental influence.
Correct Answer
Detailed Explanation
Primary growth is indeed due to the activity of apical meristems, leading to the elongation of plant parts as stated in the NCERT context, while secondary growth involves lateral meristems. Differentiation refers to the maturation of cells rather than continuous division, and heterophylly is an example of plasticity influenced by environmental factors.
