在高中生物实验中,经常使用光学显微镜(如:脂肪的鉴定,观察叶绿体与细胞质流动、细胞分裂、质壁分离及复原等).光学显微镜主要有光学系统(物镜、目镜、反光镜、通光孔等)和机械系统(镜座、镜简等)两大部分组成,在各类考试中也经常出现考察显微镜使用知识的试题. In high school biology experiments, light microscopes are often used (such as: identification of fat, observation of chloroplast and cytoplasm flow, cell division, plasmolysis and recovery, etc.). Optical microscopes mainly have optical systems (objective lenses, eyepieces, mirrors, light Holes, etc.) and mechanical systems (mirror seats, mirrors, etc.) are two major components, and examination questions of using microscopes are often found in various examinations.
