HKDSE Biology study guide
HKDSE Biology · Work through your exam, one topic at a time.
HKDSE Biology（香港中學文憑考試生物科）是香港考試及評核局（HKEAA）文憑試中甲類（Category A）高中選修科目之一。文憑試科目分為三個類別：甲類高中科目、乙類應用學習科目及丙類其他語言科目，生物科屬於甲類，與物理、化學、科學組合等並列於選修科目名單。成績採用水平參照成績匯報制度（Standards-referenced Reporting, SRR），以第1級至第5 級匯報，考評局亦製作動畫短片講解1至5 級的評級過程。評核安排包括校本評核（SBA），設有科目資訊、分數調整機制及教師手冊；評核大綱、考試報告及樣本試卷均可於考評局網站查閱。成績公布後，考生可循積分覆核及重閱答卷、上訴覆核等途徑提出申請。生物科並不受乙類科目適用年限安排（如至2027、2028或2029考試年度起適用）所影響。備考時，宜先依據考評局公布的評核大綱掌握考核範圍與評核比重，再研讀考試報告了解歷年考生表現，並以樣本試卷及歷屆試題練習作答；同時留意校本評核要求，向學校教師確認校內呈交流程與期限。本頁為獨立整理資料，並非考評局官方網站，亦不代表任何官方立場；報名、費用、考試時間表及最新安排，請以考評局官方公布為準。.

01HKDSE Biology: Core Concepts, Evidence and Data Skills
HKDSE Biology assesses how well you connect biological concepts, experimental evidence and unfamiliar contexts. The compulsory curriculum includes cell biology, genetics and evolution, human physiology, ecology and biotechnology; the exam rewards precise terminology, structure–function reasoning and data interpretation rather than recall alone. Structure fits function: relate membranes, exchange surfaces, transport systems and organelles to their roles. For example, villi increase surface area; mitochondria provide ATP; xylem vessels are dead and lignified. Energy and matter: photosynthesis stores energy in organic molecules; respiration releases it as ATP; energy flows through ecosystems while nutrients cycle. Information flow: DNA → mRNA → polypeptide; alleles determine phenotype through proteins, often interacting with the environment.

- Practice questionsA student examines a cell under a light microscope and observes a rigid structure surrounding the cell membrane that stains red with a certain dye.
- FlashcardsMagnification formula. Magnification = image size ÷ actual size.
- Cheat sheetLevels of organisation: organelle → cell → tissue → organ → organ system → organism; each level adds emergent properties not predictable from the level below alone.
- Key termsCell membrane. A thin, selectively permeable layer of phospholipids and proteins surrounding the cytoplasm, controlling which substances enter or leave the cell.
- Study planMap the HKDSE Biology compulsory syllabus into four strands (cells and molecules, genetics and evolution, organisms and environment, health and disease) and list every named process, structure and experiment you must be able to describe.
- Common mistakesThe command word 'Explain' looks similar to 'Describe', and candidates under time pressure treat the graph as something to be read aloud rather than interpreted.
- Exam-day guideBring the admission document issued to you and the identification document it specifies.
