1. Cells and Microscopy | 细胞与显微镜

Cells are the basic structural and functional units of life. In KS3 CCEA Biology, you must compare animal and plant cells, recognise organelles, and perform magnification calculations.

细胞是生命的基本结构和功能单位。在 KS3 CCEA 生物中，你必须比较动物细胞和植物细胞，识别细胞器，并计算放大倍数。

Mock Question 1: Which structure is found in a plant cell but not in an animal cell? A. Nucleus B. Cell membrane C. Cell wall D. Cytoplasm

模拟题1：以下哪个结构存在于植物细胞而不存在于动物细胞？A. 细胞核 B. 细胞膜 C. 细胞壁 D. 细胞质

Answer: C. Cell wall. Plant cells have a rigid cell wall, a large permanent vacuole and chloroplasts, which animal cells lack. This structural difference is a classic exam focus.

答案：C. 细胞壁。植物细胞有坚硬的细胞壁、大型中央液泡和叶绿体，这些动物细胞都没有。这一结构差异是经典的考试重点。

Mock Question 2: A student uses a microscope with a ×10 eyepiece lens and a ×40 objective lens. What is the total magnification? Show your working.

模拟题2：一名学生使用配备×10目镜和×40物镜的显微镜。总放大倍率是多少？请写出演算。
