Plant Growth And Development Dpp Xi — NEET/JEE Questions, Notes & Weightage
Class 11 Plant Physiology NEET weightage: High 0 questions
Covers the five major plant hormones (auxin, gibberellin, cytokinin, ethylene, ABA), their physiological effects, and growth phases (lag, exponential, stationary). Hormone-effect matching is the single most common NEET question type from this chapter.

Which plant hormone is asked about most in NEET?
Auxin and gibberellins are asked most frequently, but questions matching all five hormones to their specific physiological effects (e.g. ABA as the "stress hormone") are the most common format.
Are growth-curve questions common?
Yes — identifying the lag, exponential (log), and stationary phases from a sigmoid growth curve, and calculating growth rate, appears periodically.
What is the most commonly confused hormone pair?
Ethylene vs ABA — both are associated with senescence/stress responses, and NEET options often test whether you know which hormone does what precisely.
