Class 11 Biology — Plant Growth and Development Important Questions with Answers (Long answers)
Class 11 Biology is diversity, cell ultrastructure, biomolecules, cell cycle, plant physiology and a long human-physiology block. The rationalized book is slimmer than older reprints; this hub follows surviving units so you do not revise a deleted kingdom chapter as if it were 2026. Diagram-based MCQs (neuron, nephron, chloroplast) sit with short “give reason” items. Hidden answers, twenty a page.

Meristem, growth curve, phytohormones (auxin, gibberellin, cytokinin, ethylene, ABA), and photoperiodism. ABA is stress; ethylene is ripening. A long-day plant needs a short night. Differentiation versus dedifferentiation is a one-line pair. You are on Plant Growth and Development (Long answers), page 1 of 1 — 2 questions in this filter. Long answers model a five-mark write-up: definition, reason, one diagram or equation idea, and a closing line. Do not copy the whole block in the exam; steal the order. This view is for the night before a unit test. Phone layout: chapter chips scroll sideways, answers stay inside a tap, and the next page is a numbered link so Google and students both get a short URL. Updated for 2026 classroom practice on the rationalized NCERT.
