CAIE IGCSE 科学大纲（综合科学或协调科学）涵盖生物、化学和物理的广泛内容。Year 11 学生经常发现某些概念反复考查，同时常见陷阱可能导致本可避免的失分。本文重点分析最高频的考评领域和典型错误，帮助你集中复习、提升考试成绩。

1. Cell Structure and Organisation | 细胞结构与组织

One of the most common questions involves identifying organelles from diagrams and linking their structure to the function. You must know the differences between plant and animal cells, and how specialised cells like ciliated epithelial cells or root hair cells are adapted.

最常见的题目之一是要求从图中识别细胞器，并将结构与其功能联系起来。你必须掌握植物与动物细胞的区别，以及特化细胞（如纤毛上皮细胞或根毛细胞）的适应性。

A typical mistake is stating that ‘mitochondria provide energy’ instead of ‘mitochondria release energy through respiration’. Another frequent error is confusing the roles of chloroplasts and mitochondria, or failing to mention that the cell wall is freely permeable, not selectively permeable.

典型的错误是表述“线粒体提供能量”，而非“线粒体通过呼吸作用释放能量”。另一个常见错误是混淆叶绿体和线粒体的作用，或忘记细胞壁是自由透性的，而非选择性透性的。

When explaining osmosis, students often misuse terms like ‘concentration gradient
