Class 11 Biology NCERT Plant Growth and Development explains how plants grow, develop, and respond to environmental cues. This chapter covers types of growth, phases of development, plant hormones, photoperiodism, vernalization, and seed germination. Students also learn about the role of auxins, gibberellins, cytokinins, ethylene, and abscisic acid in regulating plant growth.
By studying Plant Growth and Development, learners understand the physiological and molecular mechanisms behind plant growth, reproduction, and adaptation. This chapter is essential for CBSE board exams and competitive exams like NEET, where plant hormones, growth patterns, and environmental responses are frequently tested.
