This 19-slide powerpoint presentation covers 'Topic 2.9 - Photosynthesis' in the 2016 IB Biology curriculum. Each slide includes the specific learning objective as well as key vocabulary that students should note. The topic has been divided into 2 sections:
A - Light
B - Photosynthesis
The presentation itself contains minimal information as it is intended to be used with teacher guidance. They are also formatted to be visually pleasing and to print well for handouts or revision. Please see the preview file for an idea of the slide aesthetic and level of detail.
As always, please let me know if you have any suggestions for improvements. These are always a work in progress!
U1: Photosynthesis is the production of carbon compounds in cells using light energy.
U2: Visible light has a range of wavelengths with violet the shortest wavelength and red the longest.
U3: Chlorophyll absorbs red and blue light most effectively and reflects green light more than other colours.
U4: Oxygen is produced in photosynthesis from the photolysis of water.
U5: Energy is needed to produce carbohydrates and other carbon compounds from carbon dioxide.
U6: Temperature, light intensity and carbon dioxide concentration are possible limiting factors on the rate of photosynthesis.
A1: Changes to the Earth’s atmosphere, oceans and rock deposition due to photosynthesis.
S1: Drawing an absorption spectrum for chlorophyll and an action spectrum for photosynthesis.
