Ib biology sl Study guides, Class notes & Summaries

This document is the complete summary required to pass the IB Biology Standard Level exams. It includes a detailed and comprehensive (yet concise) summary of Chapters 1-6 of the new textbook by Andrew Allott, as well as case studies you can mention during the exam, drawings and diagrams of relevant biological processes (such as mitosis / meiosis), tables, and class notes from a leading IB school. These notes have been used exclusively in order to achieve a 7 in the course, and have therefore ...

IB Biology SL — Topic 1 • Cell Biology with Complete Solutions Cell theory 1. All living things are composed of cells 2. Cells are the smallest unit of life 3. Cells only arise from pre-existing cells Striated muscle cell Exception to cell theory! → Muscle cells fuse to form fibres that may be very long (>300mm) → Consequently, they have multiple nuclei despite being surrounded by a single, continuous plasma membrane → Challenges the idea that cells always funct...
