1. Cell Biology Mind Map | 细胞生物学思维导图
In Cell Biology, the mind map centres on 'Cell Structure'. The main branches are: Eukaryotic cells (animal and plant), Prokaryotic cells, and Organelles. Animal cells contain a nucleus, cytoplasm, cell membrane, mitochondria and ribosomes. Plant cells have all these plus a cellulose cell wall, a large permanent vacuole and chloroplasts. Bacterial cells are prokaryotic: they lack a nucleus, have a single circular DNA molecule and may contain plasmids.
在细胞生物学中，思维导图以“细胞结构”为中心。主要分支包括：真核细胞（动物和植物）、原核细胞和细胞器。动物细胞含有细胞核、细胞质、细胞膜、线粒体和核糖体。植物细胞除此之外还有纤维素细胞壁、大型永久液泡和叶绿体。细菌细胞是原核生物：它们没有细胞核，有一条环状DNA分子，并可能含有质粒。
scopes achieve much higher resolution and magnification, revealing internal structures of organelles.
显微术是另一个关键分支。放大倍数 = 图像大小 / 实际大小。光学显微镜最高可将物体放大至约×2000，而电子显微镜能获得更高的分辨率和放大倍数，可显示细胞器的内部结构。
The cell cycle and mitosis form the 'Cell Division' branch. During interphase, DNA replicates. Mitosis produces two genetically identical daughter cells, passing through prophase, metaphase, anaphase and telophase. It is essential for growth, repair and asexual reproduction.
细胞周期和有丝分裂构成“细胞分裂”分支。间期DNA复制。有丝分裂产生两个基因相同的子细胞，依次经过前期、中期、后期和末期。它对生长、修复和无性繁殖至关重要。
Stem cells can differentiate into specialised cells. Embryonic stem cells are totipotent/pluripotent, while adult stem cells are multipotent. They have potential uses in treating diseases, though some ethical issues exist.
干细胞能分化成特化细胞。胚胎干细胞是全能的/多能的，而成体干细胞是多能的。它们在疾病治疗上有潜在用途，但存在一些伦理问题。
2. Organisation Mind Map | 组织结构思维导图
The 'Digestive System' branch shows how food is broken down. Enzymes are biological catalysts. The lock and key model explains specificity. Amylase breaks down starch into maltose, proteases break proteins into amino acids, and lipases break lipids into glycerol and fatty acids. Bile emulsifies fats and neutralises stomach acid.
“消化系统”分支展示了食物如何被分解。酶是生物催化剂。锁钥模型解释了专一性。淀粉酶将淀粉分解为麦芽糖，蛋白酶将蛋白质分解为氨基酸，脂肪酶将脂质分解为甘油和脂肪酸。胆汁乳化脂肪并中和胃酸。
The circulatory system includes the heart, blood vessels and blood. The heart is a double pump: the right side pumps deoxygenated blood to the lungs, the left side pumps oxygenated blood to the body. Arteries carry blood away from the heart under high pressure, veins return blood with valves, and capillaries allow exchange of substances.
循环系统包括心脏、血管和血液。心脏是一个双泵：右侧将缺氧血泵至肺部，左侧将含氧血泵至全身。动脉在高压下将血液带离心脏，静脉将血液送回并带有瓣膜，毛细血管实现物质交换。
In plants, the 'Organisation' of tissues includes xylem and phloem. Xylem transports water and minerals upwards, supported by lignin. Phloem transports sucrose and amino acids in both directions (translocation). Transpiration is the loss of water vapour from leaves, driven by evaporation and affected by light, temperature, humidity and wind.
在植物中，“组织”的结构包括木质部和韧皮部。木质部向上运输水和矿物质，由木质素支撑。韧皮部双向运输蔗糖和氨基酸（转运作用）。蒸腾作用是水蒸气从叶片散失，由蒸发驱动，受光照、温度、湿度和风的影响。
3. Infection and Response Mind Map | 感染与反应思维导图
Pathogens include viruses, bacteria, fungi and protists. They spread by direct contact, airborne droplets, contaminated food/water, or vectors. Bacteria produce toxins that damage cells; viruses replicate inside host cells, causing cell damage.
病原体包括病毒、细菌、真菌和原生生物。它们通过直接接触、飞沫、受污染的食物/水或媒介传播。细菌产生损害细胞的毒素；病毒在宿主细胞内复制，导致细胞损伤。
The human immune system provides non-specific defences (skin, mucus, stomach acid) and specific immune responses. White blood cells carry out phagocytosis, engulfing pathogens. They also produce antibodies that bind to antigens on pathogens, and produce antitoxins to neutralise toxins. Memory cells remain for long-term immunity.
人体免疫系统提供非特异性防御（皮肤、黏液、胃酸）和特异性免疫反应。白细胞进行吞噬作用，吞噬病原体。它们还产生抗体与病原体上的抗原结合，并产生抗毒素中和毒素。记忆细胞留存以提供长期免疫。
Vaccination introduces a small amount of weakened or dead pathogen to stimulate antibody production and memory cells, resulting in immunity. Antibiotics kill bacteria but do not work against viruses. Resistance to antibiotics arises through natural selection, so it is crucial to complete the prescribed course.
疫苗接种引入少量减弱或死亡的病原体，刺激抗体产生和记忆细胞形成，从而获得免疫。抗生素能杀死细菌，但对病毒无效。对抗生素的耐药性通过自然选择产生，因此务必完成处方疗程。
4. Bioenergetics Mind Map | 生物能量学思维导图
equation is: carbon dioxide + water → glucose + oxygen. The balanced chemical equation is:
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
光合作用在叶绿体中进行。文字表达式为：二氧化碳 + 水 → 葡萄糖 + 氧气。化学方程式为：6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂（居中显示）。
Photosynthesis is endothermic and is affected by light intensity, carbon dioxide concentration and temperature. The limiting factor concept explains that the rate is determined by the factor in shortest supply until another factor becomes limiting.
光合作用是吸热反应，受光照强度、二氧化碳浓度和温度影响。限制因子的概念解释：速率由供应最不足的因子决定，直到另一个因子成为限制因子。
Aerobic respiration releases energy from glucose using oxygen. The balanced equation is:
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy (ATP)
有氧呼吸利用氧气从葡萄糖中释放能量。方程式为：C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + 能量（ATP）。
+ carbon dioxide. Anaerobic respiration produces far less energy than aerobic respiration.
无氧呼吸在没有氧气的条件下发生。动物中：葡萄糖 → 乳酸。植物和酵母中：葡萄糖 → 乙醇 + 二氧化碳。无氧呼吸产生的能量远少于有氧呼吸。
5. Homeostasis and Response Mind Map | 稳态与反应思维导图
eurone → effector → response. Synapses use chemicals to transmit signals between neurones.
神经系统使用电脉冲。反射弧的途径为：刺激 → 感受器 → 感觉神经元 → 中枢神经系统的中继神经元 → 运动神经元 → 效应器 → 反应。突触用化学物质在神经元间传递信号。
Hormonal control of blood glucose involves insulin and glucagon. When glucose rises after a meal, the pancreas secretes insulin, which causes cells to take up glucose and the liver to convert glucose to glycogen. When glucose falls, glucagon is secreted, causing glycogen to be converted back to glucose.
血糖的激素调控涉及胰岛素和胰高血糖素。餐后血糖升高，胰腺分泌胰岛素，促使细胞摄取葡萄糖并使肝脏将葡萄糖转化为糖原。血糖降低时，分泌胰高血糖素，促使糖原转化回葡萄糖。
The menstrual cycle is regulated by oestrogen, progesterone, FSH and LH. FSH stimulates follicle growth and oestrogen production; oestrogen causes uterus lining thickening and stimulates LH release; LH triggers ovulation; progesterone maintains the lining.
月经周期受雌激素、孕激素、FSH和LH调节。FSH刺激卵泡生长和雌激素生成；雌激素使子宫内膜增厚并刺激LH释放；LH引发排卵；孕激素维持子宫内膜。
Plants respond to directional stimuli via tropisms. Phototropism (response to light) is controlled by auxin, which accumulates on the shaded side, causing cells to elongate more and the shoot to bend towards light. Gravitropism in roots causes them to grow downwards.
植物通过向性运动对定向刺激作出反应。向光性由生长素控制，生长素积累在背光一侧，使细胞伸长更多，导致茎向光弯曲。根的向地性使根向下生长。
6. Inheritance, Variation and Evolution Mind Map | 遗传、变异与进化思维导图
DNA is a double helix polymer made of nucleotides, containing the genetic code. A gene is a small section of DNA that codes for a particular protein. Chromosomes are long molecules of DNA that contain many genes. The genome is the entire genetic material of an organism.
DNA是一种由核苷酸组成的双螺旋聚合物，携带遗传密码。基因是编码特定蛋白质的一小段DNA。染色体是包含许多基因的长DNA分子。基因组是生物体的全部遗传物质。
Alleles are different versions of a gene. In a genetic cross, dominant alleles mask recessive ones. Homozygous individuals have two identical alleles, heterozygous have two different ones. Punnett squares predict the probability of offspring genotypes and phenotypes. Sex determination in humans: females are XX, males are XY.
等位基因是基因的不同形式。在遗传杂交中，显性等位基因掩盖隐性等位基因。纯合个体有两个相同的等位基因，杂合个体有两个不同的等位基因。庞纳特方格可以预测后代基因型和表现型的概率。人类的性别决定：女性为XX，男性为XY。
Variation within a species can be genetic (inherited mutations, sexual reproduction) or environmental. Natural selection acts on variation: individuals with phenotypes better suited to the environment are more likely to survive and reproduce, passing on advantageous alleles. Over generations, this leads to evolution.
物种内的变异可以是遗传的（遗传突变、有性生殖）或环境的。自然选择作用于变异：具有更适合环境的表型的个体更有可能生存和繁殖，将有利等位基因传递下去。经过许多世代，便导致进化。
7. Ecology Mind Map | 生态学思维导图
An ecosystem is the interaction of a community of living organisms with the abiotic parts of their environment. Key levels: individual, population, community, ecosystem. Organisms compete for resources, and interdependence means that changes in one species affect others.
生态系统是生物群落与非生物环境之间的相互作用。关键层次：个体、种群、群落、生态系统。生物体竞争资源，相互依存意味着某一物种的变化会影响其他物种。
The carbon cycle describes how carbon moves through the living and non-living world. Processes include photosynthesis (removes CO₂ from air), respiration and combustion (release CO₂), decomposition (returns carbon to soil), and fossilisation. The water cycle involves evaporation, transpiration, condensation and precipitation.
碳循环描述了碳如何在生物和非生物世界中转移。过程包括光合作用（从空气中移除CO₂）、呼吸和燃烧（释放CO₂）、分解（将碳归还土壤）和化石形成。水循环包括蒸发、蒸腾、凝结和降水。
Biodiversity is the variety of different species in an area. Deforestation, pollution and global warming reduce biodiversity. Conservation methods include captive breeding, habitat protection and replanting forests. Maintaining biodiversity is important for the stability of ecosystems and future resources.
生物多样性是一个区域内不同物种的多样性。森林砍伐、污染和全球变暖会降低生物多样性。保护方法包括圈养繁殖、栖息地保护和植树造林。维持生物多样性对生态系统的稳定和未来的资源至关重要。
8. Key Practical Skills Mind Map | 关键实验技能思维导图
Microscopy practical: prepare an onion epidermal cell slide, add iodine stain, and observe under different magnifications. Calculate magnification using a stage micrometre or by measuring the cell in the drawing and actual size.
显微镜实验技能：制作洋葱表皮细胞临时装片，滴加碘液染色，在不同放大倍数下观察。使用镜台测微尺或通过测量绘图和实际大小来计算放大倍数。
Osmosis in plant tissue: use potato cylinders in different sugar solutions, measure mass change. Water moves from high water potential to low water potential across a partially permeable membrane. Plot a graph to find the concentration where there is no net mass change (isotonic).
植物组织中的渗透作用：将土豆圆柱体放入不同浓度的糖溶液中，测量质量变化。水通过半透膜从高水势向低水势移动。绘制图表找出没有净质量变化的浓度（等渗浓度）。
Enzyme activity: investigate the effect of pH on amylase breaking down starch. Mix amylase and starch solution with buffer, test with iodine at fixed intervals. Record the time until starch is no longer detected. Graph time against pH; the optimum pH gives the fastest reaction.
酶活性实验：研究pH对淀粉酶分解淀粉的影响。将淀粉酶和淀粉溶液与缓冲液混合，每隔固定时间用碘液测试。记录直到检测不到淀粉的时间。绘制时间-pH图；最适pH下反应最快。
Photosynthesis rate using pondweed: place Elodea in water with sodium hydrogencarbonate, count oxygen bubbles produced per minute at different light distances. Light intensity is inversely proportional to the square of the distance (1/d²). The rate directly relates to bubble count, showing how the limiting factor affects rate.
利用水草测定光合速率：将伊乐藻放入含碳酸氢钠的水中，在不同光距下计数每分钟产生的氧气气泡数。光强度与距离的平方成反比（1/d²）。速率直接关联气泡计数，显示限制因子如何影响速率。
