Based on our years of practical tutoring at Times Edu, students should prioritise transport in cells and enzymes first because they appear across multiple topics.<\/p>\n<\/div>\n<\/div>\n<div class=\"thong-tin-dai\">\n<p class=\"tit-dai\"><strong>How to memorize biology definitions effectively?<\/strong><\/p>\n<div class=\"chi-tiet-thong-tin\">\n<p>Use retrieval practice and spaced repetition, not rereading. Write each definition in one line using mark-scheme wording, then test yourself daily until you can produce it without hesitation.A critical detail most students overlook in the 2026 exam cycle is that Cambridge rewards precise phrasing, so you must train exact recall, not approximate explanations.<\/p>\n<\/div>\n<\/div>\n<div class=\"thong-tin-dai\">\n<p class=\"tit-dai\"><strong>What is the definition of osmosis in IGCSE?<\/strong><\/p>\n<div class=\"chi-tiet-thong-tin\">\n<p>Osmosis is the net movement of water molecules from a region of higher water potential to a region of lower water potential, through a partially permeable membrane. If you replace \u201cwater potential\u201d with \u201cdilute to concentrate,\u201d you risk losing marks when the mark scheme demands the formal wording.This definition is foundational for plant turgor, kidney dialysis contexts, and cell behaviour in solutions.<\/p>\n<\/div>\n<\/div>\n<div class=\"thong-tin-dai\">\n<p class=\"tit-dai\"><strong>Define homeostasis for IGCSE Biology.<\/strong><\/p>\n<div class=\"chi-tiet-thong-tin\">Homeostasis is the maintenance of a constant internal environment within narrow limits. In extended answers, add one controlled example such as regulation of body temperature or blood glucose, but only after stating the definition clearly. From our direct experience with international school curricula, students often overwrite here and lose time.<\/div>\n<\/div>\n<div class=\"thong-tin-dai\">\n<p class=\"tit-dai\"><strong>What is the difference between aerobic and anaerobic respiration?<\/strong><\/p>\n<div class=\"chi-tiet-thong-tin\">\n<p>Aerobic respiration is the chemical reaction in cells that use oxygen to break down nutrient molecules to release energy. Anaerobic respiration is the chemical reactions in cells that break down nutrient molecules to release energy without using oxygen.The highest-mark answers also name typical products (carbon dioxide and water for aerobic; lactic acid in animals or ethanol and carbon dioxide in yeast), when the question asks for them.<\/p>\n<\/div>\n<\/div>\n<div class=\"thong-tin-dai\">\n<p class=\"tit-dai\"><strong>Are definitions required for paper 6 alternative to practical?<\/strong><\/p>\n<div class=\"chi-tiet-thong-tin\">\n<p>Yes, because Paper 6 tests practical biology using written science. You need precise definitions for terms like diffusion, osmosis, transpiration, limiting factor, variable types, and reliability concepts, since they appear in planning and analysis questions.Based on our years of practical tutoring at Times Edu, the fastest gains come from combining definition mastery with short, standard phrasing for experimental method and evaluation.<\/p>\n<\/div>\n<\/div>\n<div class=\"thong-tin-dai\">\n<p class=\"tit-dai\"><strong>Where can I find a full IGCSE Biology glossary?<\/strong><\/p>\n<div class=\"chi-tiet-thong-tin\">\n<p>The most reliable \u201cglossary\u201d is the official Cambridge 0610 syllabus and the mark scheme language used in past papers, because those reflect the phrasing that earns marks.
