Topic Title[edit | edit source]

Setting Applied context[edit | edit source]

Cell biologists explore the development and functions of cells and their related systems and interactions. Their work may include developing and testing new pharmaceuticals, diagnosing and screening diseases, testing foods and cosmetics to ensure their safety, developing fertility treatments, and carrying out cancer research, neurological research, genetic engineering, or embryology.

Syllabus Content What you need to do
•    the ultrastructure of eukaryotic and prokaryotic cells on electron micrographs, to include nuclei, smooth endoplasmic reticulum (SER), rough endoplasmic reticulum (RER), mitochondria, vesicles, lysosomes, Golgi apparatus, chloroplasts, vacuoles, cell walls, ribosomes (70S and 80S), flagella, nucleoid, plasmids, mesosomes, pili, slime capsules

•    the differences between eukaryotic and prokaryotic cell structure

•    the functions of nuclei, SER, RER, mitochondria, vesicles, lysosomes, Golgi apparatus, chloroplasts, vacuoles, cell walls, ribosomes, flagella, nucleoid, plasmids, mesosomes, pili, slime capsules

•    nucleic acid structure (DNA/RNA)

•      calculating magnification or object size using: magnification = observed size /actual size

Exploration of key ideas (must be original text, not C&P) – level checked by AQA[edit | edit source]

In general, point students towards the approach to take, as opposed to just giving them information.

DNA[edit | edit source]
