**The preview file is a pdf version of all the slides for you to review before purchasing the real thing
This powerpoint presentation covers Topic 3.8 in the IB Biology curriculum. Specifically, it covers the basics of photosynthesis and its reactants/products (see learning objectives below).
Each slide is labelled with the specific learning objective and animation/video links are provided in the slide notes. The slides are formatted to print well for handouts or revision and I can provide a pdf version upon request.
As always, please let me know if you have any suggestions for improvements. These are always a work in progress!
**IB Biology Learning Objectives:
3.8.1 – State that photosynthesis involves the conversion of light energy into chemical energy.
3.8.2 – State that light from the sun is composed of a range of wavelengths (colors).
3.8.3 – State that chlorophyll is the main photosynthetic pigment.
3.8.4 – Outline the difference in absorption of red, blue and green light by chlorophyll.
3.8.5 – State that light energy is used to produce ATP, and to split water molecules (photolysis) to form oxygen and hydrogen.
3.8.6 – State that ATP and hydrogen (derived from the photolysis of water) are used to fix carbon dioxide to make organic molecules.
3.8.7 - Explain that the rate of photosynthesis can be measured directly by the production of oxygen or the uptake of carbon dioxide, or indirectly by an increase in biomass.
3.8.8 - Outline the effects of temperature, light intensity and carbon dioxide concentration on the rate of photosynthesis.
