🧠 Exam-ready in minutes! Master the five major plant hormones and their roles in growth, development and stress responses for CAPS Grade 12 Paper 2. Perfect for data-style questions and short explanations. ▶️ Grade 12 Life Sciences Playlist:    • Matric Life Science - Exam Revision (Grade...   What we will cover 🌱 Auxins: cell elongation, apical dominance, phototropism and gravitropism, rooting powders, weedkillers 📏 Gibberellins (GA): stem elongation, seed germination (aleurone amylase), bolting and dwarf varieties 🌿 Cytokinins: cell division, delay of senescence, sink–source effects, tissue culture applications 🍐 Ethylene: fruit ripening, abscission, triple response; commercial control of ripening 🛡️ Abscisic Acid (ABA): stomatal closure, seed dormancy, drought stress responses 🔁 Tropisms and nastic movements: stimulus, receptor, growth differential, data interpretation 📈 Data skills: graphing hormone concentration vs response, identifying optima, interpreting experimental controls Resources & tips ✅ Always name the hormone, target tissue/process, and the observable outcome ✅ For tropisms, pair the stimulus with the growth side (auxin redistribution) ✅ In germination questions, link GA → amylase → starch → glucose → embryo growth ✅ In drought questions, state ABA → guard cells lose turgor → stomata close → reduced transpiration If this helped, hit 👍 and subscribe — it keeps these lessons free for everyone!
