The A level course offers a deeper understanding of Biological concepts. It allows students to apply for Biology courses (or others courses that require students to have studied Biology beyond GCSE) at university. It also allows those who simply find the subject interesting to explore their interest. The coursework is a series of practicals that give them a pass in practical competencies at the end of the course. It does not contribute any marks to the final grade, but allows students to undertake scientific courses at university. Topics covered over the two years of the course include: • Biological molecules: This topic introduces students to all the main Biological molecules that are common to living things. The vital role of water throughout all Biological systems will also be considered. • Cells: This topic compares the structure of prokaryotic and eukaryotic cells, considers cell division and explores how cells interact with their surroundings. • Organisms exchange substances with their environment: This topic considers moving materials into and out of cells by looking at gas exchange, digestion and mass transport. • Genetic information: The relationship between DNA, proteins and phenotype is explored. • Energy transfers in and between organisms: This topic looks at the fundamental energy transfer processes of photosynthesis, respiration, food chains and food webs and nutrient cycles. • Organisms respond to changes in their internal and external environments: The structure and function of the nervous system, muscle contraction and the way humans maintain a constant internal environment by homeostasis is covered in this. In contrast to the way humans respond to changes in the environment, the way plants respond to stimuli by the use of hormones is also studied. • Genetics, populations, evolution and ecosystems: This topic explores genetic inheritance and genetic variability. • Control of gene expression: This topic explores the way that the expression of genes is controlled.
