NEET Focus – Plant Growth and Development
This chapter is highly scoring in NEET due to direct NCERT-based questions.
Important NEET Exam Tips
- Plant hormones (Auxin, GA, Cytokinin, Ethylene, ABA) contribute 70%+ of PYQs.
- Memorise one key function + one antagonistic pair per hormone.
- Ethylene = gaseous hormone + triple response + fruit ripening (very high yield).
- ABA = stress + dormancy + stomatal closure (frequently repeated).
- Photoperiodism questions focus on night length, leaves as site, phytochrome.
- Vernalisation questions often confuse temperature vs photoperiod — read carefully.
- Expect 1–2 direct PYQs every year from this chapter.
Strategy: Revise NCERT tables, keywords, and hormone antagonism before the exam.
