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...

Nephelometry involves the measurement of A. Light scatter B. Atomic absorption C. Light absorption D. Light transmission - C. Light absorption When light strikes a particle in a solution, it can be absorbed, transmitted, reflected, or scattered. Nephelometry is used to measure the light scattered by particles in a solution. It is useful for measuring protein levels in fluids, and antigen-antibody complexes Most potent activator enzyme is A. Magnesium B. Sodium C. Potassium D. AOTA -...

IB Biology Topic 1: Cell Biology Questions and Answers Already Passed What does cell theory state? That cells are the smallest possible unit of life and that living organisms are made up of cells. What are unicellular organisms? Give two examples Unicellular organisms are organisms with only one cell, such as Paramecium and Chlamydomonas. In unicellular organisms the one cell carries out all of the functions of life. Why are large organisms multicellular? Because of surface area to ...
