CIE IGCSE Biology 0610 — Chapter 8: Transport in Plants — Content Review Guide for Revision
CIE IGCSE Biology 0610: Transport in Plants Content Review Guide (Ch. 8)Master transpiration, xylem, phloem, and the cohesion-tension theory—with precision.Transport in plants is a core topic that appears consistently across both Paper 2 (MCQ) and Paper 4 (Extended Theory). This focused content review guide delivers everything you need to understand how water and organic nutrients move through plants—with the exact language examiners expect.What’s Inside: Transpiration—Definition & Driving Force: Clear explanation of water loss from leaves, the water potential gradient, and the transpiration stream. Includes the complete 6-step mechanism. Cohesion-Tension Theory: Step-by-step breakdown of how water moves from roots to leaves—covering cohesion, tension, and adhesion. Includes key terms and the mark-scheme chain. Stomata—Opening & Closing Mechanism: Detailed explanation of guard cell turgor, the role of light and CO₂, and why stomata close at night or under drought stress. Includes the hormone ABA. The 4 Factors Affecting Transpiration Rate: Temperature, light intensity, humidity, and wind speed—each with a detailed mechanism and summary table. Includes the critical point that humidity is the only factor that decreases transpiration when increased. Xylem—Structure & Function: What it transports (water + mineral ions), structural features (dead cells, lignified walls, no end walls), and why each feature suits its function. Phloem & Translocation: What it transports (sucrose, amino acids), source-to-sink mass flow mechanism, and the role of companion cells. Xylem vs. Phloem Comparison Table: 10 key differences—alive/dead, lignified/not, one-way/two-way, organic/inorganic, active/passive—ready for 6-mark comparison questions. Common Exam Errors—Side-by-Side Corrections: Four of the most frequent mistakes students make on plant transport questions, with the correct answers examiners expect. This guide is perfect for: Students who need a clear, concise, no-fluff review of a high-priority syllabus chapter. Teachers looking for a ready-to-use content summary to support classroom teaching or revision sessions. Tutors who need a structured resource to help students master transpiration mechanisms, xylem/phloem distinctions, and factor analysis. Stop losing marks to vague explanations and confused terminology. Get the precise language and clear frameworks you need to answer any transport in plants question with confidence.Format: PDF (Instant Download)
