Botany8–10 questions per year (~9% of Biology)

NEET Plant Physiology.

Photosynthesis, respiration, mineral nutrition, plant growth and movements. Heavy on biochemistry and process diagrams.

Plant Physiology is one of the highest-yield Biology chapters. Photosynthesis (light reactions, Calvin cycle, C3/C4/CAM differences) and respiration (glycolysis, Krebs cycle, electron transport chain) are tested almost every year. Plant hormones (auxin, gibberellin, cytokinin, ABA, ethylene) and their applications are NCERT-only and very predictable.

NCERT chapters to cover
