Plant hormones

पादप हार्मोन

In this Class 10 Science topic from the chapter Control and Coordination, students learn how plants coordinate growth and respond to their surroundings without a nervous system. The topic introduces plant hormones such as auxin, gibberellin, cytokinin, abscisic acid and ethylene, explaining their roles in cell growth, seed germination, flowering, dormancy, fruit ripening and leaf fall. Students also connect these chemical signals with responses such as phototropism and geotropism, building a clear understanding of plant regulation and movement.
