Organisms, Energy and Environment (3rd Edition) Taylor, Green, Stout and Soper Advanced Biology: Principles and Applications (2nd edition) Clegg and Mackean H2 Biology Syllabus 9477 (2025) Candidates should be able to use the knowledge gained in the following section(s) in new situations or to solve related problems. Related Topics Genetics and Inheritance Concepts The Structure of Nucleic Acids and Gene Expression Organisation of Genomes The Cell Cycle Energy and Equilibrium Transformation of Energy between the Environment and Organisms Infectious Diseases Viral diseases (e.g. Influenza, HIV) Learning Outcomes 1A. Organelles and Cellular Structures a. Outline the cell theory with the understanding that cells are the smallest unit of life, all the cells come from pre-existing cells; and living organisms are composed of cells. b. interpret and recognise drawings, photomicrographs and electron micrographs of the cytoplasm (cytosol) and cellulose cell wall, and the following membrane systems and organelles: rough and smooth endoplasmic reticulum, Golgi body, mitochondria, ribosomes, lysosomes, chloroplasts, cell surface membrane, nuclear envelope, centrioles, nucleus and nucleolus (for practical assessment, candidates may be required to operate a light microscope, mount slides and use an eyepiece graticule and a stage micrometer) c. Outline the functions of the membrane systems and organelles listed in (b). d. Describe the structure of a typical bacterial cell (small and unicellular, peptidoglycan cell wall, circular DNA, 70S ribosomes and lack of membrane -bound organelles) (KIV: Organisation of Genomes – Prokaryotes)
