Life Science Grade 12 | Plant Responses to the Environment CAPS — Paper 1 Exam Revision

Ace your exam! Master Plant Responses to the Environment for Grade 12 CAPS or NSC — Paper 1. Clear notes on hormones, tropisms, photoperiodism, and exam-style data questions with memo keywords 🌿📚 ▶️ Grade 12 Life Sciences Playlist:    • Matric Life Science - Exam Revision (Grade...   What you will learn 🌱 Plant hormones: auxins, gibberellins, cytokinins, abscisic acid, ethylene — where made, main actions 🌤️ Tropisms: phototropism, geotropism or gravitropism, hydrotropism, thigmotropism — role of auxin and differential growth ⏱️ Nastic movements: rapid turgor changes vs growth responses, examples like Mimosa 🕰️ Photoperiodism: short-day vs long-day vs day-neutral plants, role of phytochrome Pr and Pfr, critical night length 🌾 Dormancy and germination: ABA in dormancy, gibberellin in breaking dormancy and stimulating germination 🧪 Investigations: coleoptile experiments, decapitation and mica barrier setups, unilateral light experiments, controls and variables 📝 Memo keywords: auxin, differential growth, apical dominance, phototropism, gravitropism, phytochrome, Pfr to Pr, critical photoperiod, nastic, turgor, dormancy, germination, gibberellin, ABA ❗ Common pitfalls: mixing tropisms with nastic movements, forgetting that phototropism is growth based, confusing photoperiod with light intensity Exam technique — Paper 1 For experiments: identify IV, DV, controls, and say how to improve reliability repeats and sample size For graphs and tables: quote numbers and trends and link to the hormone or response named For explanations: structure → function → how it leads to the observed response How to use this video Pause at each question, attempt it, then mark with our checklist to maximise your score ✅ Hashtags #Matric #Grade12 #LifeSciences #CAPS #NSC #MatricRevision #Paper1 #PlantResponses #Tropisms #Photoperiodism #PlantHormones #ExamTips #PastPapers #Matric2025 #Matric2026 Tags Matric Life Sciences, Grade 12 Life Sciences, Life Sciences CAPS, NSC Life Sciences, Paper 1 plant physiology, Plant responses Grade 12, Plant hormones auxin gibberellin ABA, Tropisms phototropism gravitropism hydrotropism thigmotropism, Nastic movements, Photoperiodism phytochrome, Dormancy and germination, Coleoptile experiments, Apical dominance, Differential growth, Exam tips Life Sciences, Past papers Life Sciences
