Biology SL

Form and function

IB Biology organizing theme: structure-function relationships from molecules to ecosystems.

Use membrane structure to explain transport Explain enzyme activity and factors affecting rate Use microscopy scale, magnification, and resolution Analyse carbohydrates, lipids, and proteins Explain DNA structure and replication Find the rate of oxygen production from a graph Read two points off an oxygen-produced vs time graph and find the rate of photosynthesis as oxygen over time (the gradient). Find the rate of transpiration from a graph Read two points off a water-lost vs time graph and find the transpiration rate as water lost over time (the gradient). Explain gas exchange surfaces and ventilation Analyse neurons, synapses, and signalling
