Photosynthesis

• Photosynthesis- the production of carbohydrates from carbon dioxide and water in the presence of chlorophyll using light energy.

6CO2 + 12H2O ---> C6H12O6 + 6O2 + 6H2O

• Albert Einstein- proposed the Particle Model of Light in 1905.– Light is composed of particles of energy called photons.– Visible light has different photon wavelengths.

Please note that due to differing operating systems, some animations will not appear until the presentation is viewed in Presentation Mode (Slide Show view). You may see blank slides in the “Normal” or “Slide Sorter” views. All animations will appear after viewing in Presentation Mode and playing each animation. Most animations will require the latest version of the Flash Player, which is available at http://get.adobe.com/flashplayer.
