Follows the Pearson Edexcel International AS/A Level Specification. Learning outcome: 3.1 Know that all living organisms are made of cells, sharing some common features. 3.2 Understand how the cells of multicellular organisms are organised into tissues, tissues into organs and organs into organ systems. 3.3 (i & ii) Know and understand the function of the ultrastructure of eukaryotic cells, including nucleus, nucleolus, ribosomes, rough and smooth endoplasmic reticulum, mitochondria, centrioles, lysosomes and Golgi apparatus. 3.4 Understand the role of the rough endoplasmic reticulum (rER) and the Golgi apparatus in protein transport within cells, including their role in the formation of extracellular enzymes. 3.5 (i) & (ii) Know and understand the function of the ultrastructure of prokaryotic cells, including cell wall, capsule, plasmid, flagellum, pili, ribosomes and circular DNA. 3.6 Be able to recognise the organelles in 3.3 from electron microscope (EM) images. 3.7 (i) Know how magnification and resolution can be achieved using light and electron microscopy. 3.7 (ii) Understand the importance of staining specimens in microscopy Core Practical 5: 3.8 (i) Use a light microscope to make observations and labeled drawings of suitable animal cells.
