Biology: Electron Microscope Assignment - Cell Structure Analysis

This assignment provides a detailed analysis of electron microscopy techniques and their applications in biology. The first section classifies chemical fixatives, including aldehydes and heavy metal fixatives, detailing their molecular formulas, properties, reactions, advantages, and disadvantages. The second section identifies and describes various cell structures, such as the nucleus, nucleolus, and cell membrane. The third section compares and contrasts two images, focusing on the Golgi apparatus and identifying structural differences, including vacuole and mitochondria sizes. The final section examines the structures in two images, identifying a macrophage cell and a lysosome, and discusses their functions, including phagocytosis and the breakdown of foreign materials, along with the identification of artifacts. The assignment concludes with a comprehensive list of references.
