Overview

AS Biology extends foundational knowledge with a more detailed and analytical approach. Students explore biological systems, molecular biology, and cell physiology in greater depth.

Key Topics

• Cell Structure and Function: Organelles, microscopes, prokaryotes vs eukaryotes
• Biological Molecules: Water, carbohydrates, lipids, proteins, nucleic acids
• Enzymes: Mode of action, factors affecting enzyme activity
• Membranes and Transport: Fluid mosaic model, diffusion, osmosis, active transport
• DNA, RNA, and Protein Synthesis
• Cell Division: Mitosis and meiosis
• Gas Exchange and Transport: In humans and plants
• Immune System: Antibodies, vaccines, immune response
• Genetics: Mendelian genetics, monohybrid crosses, codominance
• Ecology: Sampling techniques, biodiversity, ecosystems

Skills Developed

• Critical analysis of experimental design
• Interpretation of more complex data sets and biological trends
• Writing detailed lab reports and evaluating experimental results
• Application of biological concepts to unfamiliar contexts

Objective

To develop analytical thinking and prepare students for higher-order biological study in A2 and beyond.
