Development — Prelims Strategy
Prelims Strategy
To effectively tackle NEET questions on 'Development', a multi-pronged strategy is recommended. First, ensure a crystal-clear understanding of core definitions: growth, development, differentiation, dedifferentiation, redifferentiation, and especially plasticity.
Don't just memorize; understand the underlying biological significance of each. Second, pay close attention to examples. For plasticity, remember specific plants exhibiting heterophylly (e.g., buttercup for environmental, cotton/larkspur for developmental).
Third, master the functions of all five major Plant Growth Regulators (Auxins, Gibberellins, Cytokinins, ABA, Ethylene) and their interactions. Create a mental map or a table summarizing their primary roles in different developmental stages (e.
g., which PGR promotes seed germination vs. dormancy). Fourth, understand the impact of environmental factors like light (photoperiodism, critical day length, short-day/long-day plants) and temperature (vernalization, site of perception).
For conceptual questions, read each option carefully, eliminating distractors by recalling precise definitions and examples. For questions involving PGR interactions (e.g., tissue culture ratios), remember the specific outcomes associated with different ratios.
Practice identifying the 'odd one out' or the 'most appropriate' statement. Avoid common traps like confusing growth with development, or misattributing PGR functions.
