📚 SQA Year 10 Biology: Vocabulary Terminology Quick Memorisation Guide | SQA Year 10 生物：词汇术语速记指南
Struggling to retain all the biology vocabulary for your SQA National 5 (Year 10 equivalent) exam? You are definitely not alone. Biology can feel like a foreign language, packed with terms such as 'photosynthesis', 'mitosis', and 'haemoglobin'. The good news is that a handful of clever memorisation techniques can transform these long words into easy-to-recall building blocks. This guide breaks down key vocabulary groups and provides word roots, mnemonics, and visual tricks to accelerate your learning.
你是否发现 SQA National 5（相当于 Year 10）生物考试中的大量术语很难记住？你绝不是一个人。生物学就像一门新语言，充斥着“光合作用”、“有丝分裂”和“血红蛋白”这些词。好在通过一些巧妙的记忆技巧，这些长单词可以变成易于回想的知识模块。本指南将关键词汇分组，并提供词根、助记法和视觉窍门，帮助你提速学习。
1. The Power of Word Roots and Prefixes | 词根与前缀的力量
Biology terms are not random; most are stitched together from Greek or Latin word parts. Once you learn the most common roots, you can decipher new vocabulary on the spot. For instance, 'photo-' means light and 'synthesis' means putting together, so photosynthesis literally means building substances using light. This method reduces the memory load dramatically.
生物术语并非随机拼凑，它们大多由希腊语或拉丁语的词素组合而成。一旦你掌握了常见的词根，就能当场破解生词。比如“photo-”表示光，“synthesis”表示组合，因此光合作用字面意思就是利用光构建物质。这种方法能极大地减轻记忆负担。
Make flashcards of these high-frequency building blocks: 'cyto-' (cell), '-ology' (study of), 'mono-' (one), 'poly-' (many), 'hyper-' (above normal), 'hypo-' (below normal), 'endo-' (inside), 'exo-' (outside), 'inter-' (between), and 'intra-' (within). Tacking on '-ase' gives you an enzyme, while '-ose' signals a sugar such as glucose.
把这些高频构件做成卡片：“cyto-”（细胞）、“-ology”（学问）、“mono-”（单）、“poly-”（多）、“hyper-”（高于正常）、“hypo-”（低于正常）、“endo-”（内）、“exo-”（外）、“inter-”（之间）、“intra-”（内部）。词尾加上“-ase”就成了酶，而“-ose”则暗示糖类，如葡萄糖。
Mastering this approach means you can decode something like 'hypertonic' (hyper- above + ton- tension/strength) as a solution with higher solute concentration, and 'hypotonic' as one with lower concentration — without having to memorise each word in isolation.
掌握了这种方法，你就能拆解出“hypertonic”（高渗的）意为溶质浓度较高的溶液，“hypotonic”为浓度较低的溶液——根本不需要孤立地死记硬背每一个词。
2. Cellular Structures and Their Mnemonics | 细胞结构及其助记符
Animal and plant cells share several organelles, but you need to name them quickly and spell them correctly. Connect each structure to a short story or image. The nucleus, derived from Latin 'nux' (kernel), is the control centre that houses DNA. Picture a nut inside the cell giving orders.
动物细胞和植物细胞共享多种细胞器，但你需要快速说出它们的名称并正确拼写。给每种结构配上一个短故事或图像。细胞核源自拉丁语“nux”（核仁），是容纳 DNA 的控制中心。想象细胞里有一颗发号施令的果仁。
Mitochondria (singular: mitochondrion) are the sites of aerobic respiration. Use the sound 'mighty' to remember they are mighty energy factories. Chloroplasts, which contain chlorophyll for photosynthesis, are only in plant cells — think 'chloro' for green and 'plast' meaning a moulded structure.
线粒体（单数：mitochondrion）是有氧呼吸的场所。利用“mighty”（强大的）的发音，记住它们是强大的能量工厂。叶绿体含有叶绿素，用于光合作用，只存在于植物细胞——记住“chloro”表示绿，“plast”表示可塑的结构。
Ribosomes make proteins and can float freely or sit on the rough endoplasmic reticulum. 'Ribo' sounds like 'ribonucleic acid', a clue to their job. The cell membrane controls what enters and leaves. Its alternative name, plasma membrane, reminds you it is a partially permeable barrier.
核糖体制造蛋白质，可以自由漂浮或附着在粗糙内质网上。“Ribo”听起来像“核糖核酸”，暗示了它的功能。细胞膜控制物质进出；它的另一个名字质膜，提醒你这是一道选择透过性屏障。
For plant cells, remember the rigid cell wall made of cellulose (not polysaccharide alone, but specifically cellulose). The large permanent vacuole stores cell sap and maintains turgor pressure: think 'vacuum' + 'ole' (little) to picture a storage sac.
对于植物细胞，记住坚硬的细胞壁由纤维素构成。那个永久性的大液泡储存细胞液并维持膨压：联想“vacuum”（真空）加“ole”（小），想象一个储存囊。
3. Enzymes and Digestive Terms | 酶与消化术语
Enzymes are biological catalysts, and every digestive enzyme fits its substrate like a key fits a lock. The lock-and-key model is easier to recall if you visualise a real key entering a lock. Enzymes are not used up, which is why they can be recycled in reactions.
酶是生物催化剂，每种消化酶与其底物的匹配就像钥匙开锁一样。如果你想象一把真正的钥匙插入锁孔，就能更容易地记住锁钥模型。酶不会被消耗，因此可以在反应中被反复利用。
Amylase breaks starch down into maltose. 'Amyl-' means starch, and 'malt' connects to malt sugar. Protease digests protein: 'prote-' comes from Greek for 'first' (protein is the first substance of life). Lipase acts on lipids (fats): 'lip-' relates to fat. Notice the consistent '-ase' ending.
淀粉酶将淀粉分解为麦芽糖。“Amyl-”意为淀粉，“malt”则联系到麦芽糖。蛋白酶消化蛋白质：“prote-”源自希腊语“第一”（蛋白质是生命的基本物质）。脂肪酶作用于脂质（脂肪）：“lip-”与脂肪相关。注意它们一致的“-ase”结尾。
gestion are small, soluble molecules that can be absorbed into the blood. Use the sentence 'I AM a PRO' Peptides/amino acids. Bile is not an enzyme; it is produced by the liver and stored in the gall bladder to emulsify fats. Emulsification increases surface area — imagine breaking a giant oil blob into tiny droplets.
消化产物是小分子、可溶的物质，能被吸收进入血液。用“I AM a PRO”来联系：淀粉酶 → 麦芽糖、蛋白酶 → 肽/氨基酸。胆汁不是酶，由肝脏产生并储存在胆囊中，用于乳化脂肪。乳化增大表面积——想象把巨大的油滴分解成小液滴。
4. Genetics Vocabulary: From Alleles to Zygotes | 遗传学词汇：从等位基因到受精卵
Genetics vocabulary often trips up students, but the terms are logical once you break them down. A gene is a section of DNA that codes for a protein. An allele is an alternative form of a gene. 'Allele' sounds like 'alternate' — just drop the 'rn'.
遗传学词汇经常绊倒学生，但拆解之后它们逻辑清晰。基因是编码蛋白质的一段 DNA。等位基因是基因的替代形式。“Allele”听起来像“alternate”——去掉中间的音节就行。
es you have (e.g. Bb), while phenotype is the physical expression (e.g. brown eyes). Think 'Phenotype = Physical appearance'. Dominant alleles mask recessive alleles: dominant 'dominates', recessive 'retreats' . Homozygous means the two alleles are the same (homo- same), and heterozygous means they are different (hetero- different).
基因型是你拥有的等位基因组合（如 Bb），表型是外在的表现（如棕色眼睛）。记住“Phenotype = Physical appearance”（表型=身体外观）。显性等位基因掩盖隐性等位基因：显性“支配”了，隐性“退缩”了。纯合子意味着两个等位基因相同（homo-同），杂合子意味着不同（hetero-异）。
Genetic diagrams like Punnett squares show possible offspring genotypes. Monohybrid crosses look at one characteristic. The term 'gamete' for sex cell can be remembered by 'gaMETE' — you met because of a gamete. A zygote is a fertilised egg, the first cell of a new individual.
彭尼特方格等遗传图解显示可能的后代基因型。单因子杂交针对一种性状。配子（gamete）可以这样记：“gaMETE”——你之所以存在是因为配子的相遇。受精卵是受精后的卵细胞，是新个体的第一个细胞。
5. Ecological Relationships and Energy Flow | 生态关系与能量流动
In ecosystems, organisms are described by how they obtain energy. Producers (autotrophs) make their own food via photosynthesis. 'Auto-' means self, and '-troph' means feeder — self-feeder. Consumers (heterotrophs) must eat others: 'hetero-' means other. Decomposers break down dead matter, returning nutrients to the soil.
在生态系统中，生物按获取能量的方式来描述。生产者（自养生物）通过光合作用制造自己的食物。“Auto-”意为自我，“-troph”意为食客，即自食其力者。消费者（异养生物）必须摄取其他生物：“hetero-”意为其他。分解者分解死物，把养分归还土壤。
A food chain shows a linear energy path: arrow points in the direction of energy flow. Think 'the arrow is eaten by'. The first trophic level is always a producer. Pyramid of numbers, biomass, and energy can be recalled by singing the familiar pyramid shape: the base is broad because energy is lost at each level.
食物链展示线性的能量路径：箭头指向能量流动的方向。记住“箭头被吃掉”。第一营养级总是生产者。数量金字塔、生物量金字塔和能量金字塔可以通过金字塔形状来记忆：由于每一级都有能量损耗，底部总是最宽。
Key terminology includes population (members of the same species in an area), community (all populations living together), and ecosystem (community plus abiotic factors). Relate 'population' to 'people', which helps you remember it is a group of the same kind. Niche is an organism’s role and position in the ecosystem — like a job within the community.
关键术语包括种群（同一区域中同一物种的成员）、群落（共同生活的所有种群）和生态系统（群落加非生物因素）。把“population”与“people”联系起来，这有助于记住它是同一类生物的群体。生态位是生物在生态系统中的角色和位置，就像群落里的一份工作。
6. Transport in Plants: Xylem and Phloem Tricks | 植物运输：木质部与韧皮部窍门
Two transport tissues operate inside plants, and mixing them up is a common mistake. Xylem transports water and dissolved minerals from roots upwards. Use the mnemonic: 'Xylem goes up like a xylophone's pipes, carrying water'. Xylem vessels are dead cells with hollow lumens, strengthened by lignin.
植物的两种输导组织经常被混淆。木质部将水和溶解的矿物从根部向上运输。用这个助记：“木质部像木琴的管子一样向上，输送水分”。木质部导管是死细胞，具有中空腔，由木质素加固。
rose) from leaves to the rest of the plant, both up and down. This is translocation. Think 'Phloem = Food flows' . The phloem is made of living cells with sieve plates and companion cells for support. The word 'sieve' suggests lots of tiny holes — exactly the structure.
韧皮部将糖（主要是蔗糖）从叶片运往植物各处，既向上也向下，这被称为输导作用。联想“Phloem = Food flows”（食物在流动）。韧皮部由活细胞构成，含有筛板和伴胞提供支持。“筛”这个词意味着许多小孔——正是它的结构。
Transpiration is the evaporation of water from leaf surfaces, creating a pulling force that draws water up the xylem. The cohesion-tension theory explains this. Think of a chain of water molecules pulling each other up. Wilting happens when water loss exceeds uptake, so cells lose turgor and leaves droop.
蒸腾作用是水分从叶片表面蒸发，产生拉力，将水向上吸进木质部。内聚力-张力理论解释了这一点。想象一串水分子互相拉着向上爬。当水分散失超过吸收时，细胞失去膨压，叶片下垂，发生萎蔫。
7. Respiration and Photosynthesis Equations | 呼吸作用与光合作用方程式
These two essential processes can be remembered as reverse equations of each other. Aerobic respiration releases energy from glucose using oxygen. The word equation is clear, but you must recall the balanced symbol equation too. Write it out as:
这两个关键过程可以视作互为反向的方程式。有氧呼吸利用氧气从葡萄糖中释放能量。文字方程式很清晰，但你也必须记住配平的符号方程式。书写如下：
Aerobic Respiration: C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy (ATP)
Think 'respiration = release' e and water to produce glucose and oxygen, driven by light energy absorbed by chlorophyll:
记住“呼吸作用 = 释放”，因为释放出二氧化碳和水。光合作用利用二氧化碳和水，在叶绿素吸收的光能驱动下，生成葡萄糖和氧气：
Photosynthesis: 6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂
Pay attention to the limiting factors of photosynthesis: light intensity, carbon dioxide concentration, and temperature. To recall, use the abbreviation 'LCT' — Light, CO₂, Temperature. A limiting factor is the one that is in the shortest supply and restricts the rate of the reaction. When a question asks you to explain a graph of photosynthesis, always mention enzyme activity and denaturation at high temperatures above the optimum.
注意光合作用的限制因素：光照强度、二氧化碳浓度和温度。可以用缩写“LCT”来记忆。限制因素是指供给最短缺并制约反应速率的因素。当考题要求解释光合作用图表时，务必提及酶活力以及在超过最适温度时酶会变性。
8. Mitosis vs. Meiosis Visual Memory Aids | 有丝分裂与减数分裂视觉记忆辅助
Cell division terminology causes confusion because the stages look similar. Mitosis produces two genetically identical daughter cells for growth and repair. Use the phrase 'MITosis makes my toes' — your toes grow through mitosis, and the cells are identical to the original.
细胞分裂术语容易混淆，因为各个阶段看起来很相似。有丝分裂产生两个遗传上相同的子细胞，用于生长与修复。用这句话记住：“MITosis makes my toes”——你的脚趾通过有丝分裂生长，细胞与原细胞完全相同。
Meiosis produces four genetically varied haploid (n) gametes. Remember 'MEiosis makes Me special' because it creates variation for sexual reproduction. The chromosome number is halved, which is why it's called a reduction division. Key stages: PMAT (Prophase, Metaphase, Anaphase, Telophase), but in meiosis, the cell divides twice (Meiosis I and II).
减数分裂产生四个遗传上不同的单倍体（n）配子。记住“Meiosis makes Me special”，因为它为有性生殖创造了变异。染色体数目减半，因此被称为减数分裂。关键阶段为 PMAT（前期、中期、后期、末期），但减数分裂中细胞连续分裂两次（减数第一次分裂和减数第二次分裂）。
Use this trick: Mitosis — one division, two cells, diploid. Meiosis — two divisions, four cells, haploid. Draw two sets of PMAT and label them. Remember that haploid means half the chromosome number (n), while diploid is the full set (2n).
用这个窍门：有丝分裂——一次分裂，两个细胞，二倍体。减数分裂——两次分裂，四个细胞，单倍体。画出两组 PMAT 并标注。记住单倍体是染色体数目的一半（n），二倍体是整套（2n）。
9. Disease and Immunity Key Terms | 疾病与免疫关键术语
Pathogens are disease-causing microorganisms such as bacteria, viruses, and fungi. The name comes from 'patho-' (suffering) and '-gen' (producer). An antigen is a molecule, often a protein, on the surface of a pathogen that triggers an immune response.
病原体是引起疾病的微生物，如细菌、病毒和真菌。该词来自“patho-”（痛苦）和“-gen”（产生者）。抗原是病原体表面的分子，通常是蛋白质，能触发免疫反应。
Antibodies are Y-shaped proteins produced by lymphocytes that bind to specific antigens. The 'anti-' prefix means against, and 'body' here refers to a defensive molecule. Phagocytes are white blood cells that engulf and digest pathogens; 'phago-' means eating, and '-cyte' means cell — literally a cell that eats.
抗体是淋巴细胞产生的 Y 形蛋白质，能与特定抗原结合。“anti-”前缀表示抵抗，“body”这里指防御分子。吞噬细胞是吞噬并消化病原体的白细胞；“phago-”意为吃，“-cyte”意为细胞，即会吃的细胞。
Vaccination involves introducing a harmless form of an antigen to stimulate memory lymphocyte production. When the real pathogen strikes, the secondary response is faster and stronger. The term 'immunity' comes from 'immunis', meaning exempt or protected. Antibiotics are medicines that kill bacteria but do not work on viruses — remember 'anti' + 'biotic' (against life), effective only on bacterial life.
疫苗接种涉及引入无害的抗原形式，以刺激记忆淋巴细胞的产生。当真正的病原体入侵时，二次免疫反应更快更强。“免疫”一词源于“immunis”，表示豁免或受到保护。抗生素是杀死细菌的药物，但对病毒无效——记住“anti”+“biotic”（抗生命），只对细菌生命有效。
