A Level Biology goes into much more detail than you will have covered about living systems and processes at GCSE. It will give you the skills to make connections and associations with all living things around you. Biology literally means the study of life and being such a broad topic you are bound to find a specific area of interest. The content is divided into eight sections: Biological molecules e.g. triglycerides, monosaccharides, Cells, Organisms exchange substances with their environment, Genetics—variation and relationships between organisms, Energy transfer e.g. photosynthesis respiration, Response to change e.g. nervous co-ordination, Homeostasis, Genetics population evolution and ecosystems, control of gene expression.
