O水准生物可能是大部分scholar最头疼的一门science-要背的内容之多堪比文科,而且背半天好像答题还是拿不到分。考前的最后冲刺阶段,千万不能浪费时间在漫无目的的啃书本上,重要的是study smart!
1.看考纲
生物的每一章节标题下面都有LearningOutcome,这也就是O考的考纲。在复习每一章节之前一定要弄清楚重点在哪里,不要浪费时间在没有用的细节上。看完一章之后再回
Learning Outcome看自己能不能简洁明了地回答每一个问题。

2、创建知识系统
主要生物知识系统架构
结构-特点-功能-影响因素:
2.1---细胞
1.细胞器结构与功能
2.Mitosis and Meiosis stages and comparison
2.2---植物
Transport: Osmosis, Transpiration ofwater:root, xylem,leaf(intercellular air space), stomata
Nutrition: Photosynthesis: structure of the leaf, chloroplast
Reproduction: Asexual-> advantages; Sexual:organ andtissuestructure, adaptations, advantages
Eg 1: Transport
2.3---动物(briefhighlight)
Nutrition:digestion andassimilation: digestive track,
*small intestinestructure and adaptation
*Hormonal controlfor blood sugar regulation
Transport:Respiration-mitochondria and the productionof CO2 or lactic acid (and then finally CO2),CO2 transport, gaseous exchange atthe longs
Excretion:kidney structure andadaptation. Implicationof kidney failure
* Hormonal andNeural control forosmoregulation
Homeostasis:
Hormonalcontrol(glands-chemical signal-target organ-response)
Neural control
involuntary:stimuli-sensoryneuron - nerveimpulse-synapse (conversion from electrical signal to chemicalsignal then backto electrical signal in the next neuron)-central nervoussystem (relayneuron)-synapse-motor neuron - muscle/gland
Involuntary VSVoluntary responses
* note thecoordination of neural andhormonal control and the physiological changeseffected in response to differentsignals and stimuli ->ultimately ensuringsurvival/maintaining a balancedinternal environment
Reproductive System:
Reproductive organstructure and adaptation
***Hormonalcontrolfor the menstrual cycle
