Learning Outcomes of Syllabus 9477 (H2 Biology)

(a) outline the cell theory with the understanding that cells are the smallest unit of life, all cells come from pre-existing cells and living organisms are composed of cells

(b) interpret and recognise drawings, photomicrographs and electronmicrographs 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)
