Instructions: Please provide clear explanation of your assigned assessment statement on the page the statement links to (below). 

• Try to use bulletted lists; be concise, instead of long, narrative, prose. 

• Include at least a single great image for each assessment statement (you are welcome to use images in the "photosynthesis" folder on this wiki. 

• Either provide a clear link to the source of the image, or the URL above the image (if you use external images).

• Add at least one link to at least another source of excellent information on your assessment statement.

Photosynthesis overview

3.8.1  State that photosynthesis involves the conversion of light energy into chemical energy (Jae Min)

8.2.2  State that photosynthesis consists of light-dependent and light-independent reaction. (Kyung)

Light Absorption by Chlorophyll

8.2.7  Explain the relationship between the action spectrum and the absorption spectrum of photosynthesis pigments in green plants. (Peter)

3.8.2  State that light from the Sun is composed of a range of wavelengths (colors) (Rachel)

3.8.3  State that chlorophyll is the main photosynthetic pigment (Lizzy)

3.8.4  Outline the differences in absorption of red, blue and green light by chlorophyll (Jane)

Light-Dependent Reactions

8.2.3  Explain the light dependent reactions. (Jennifer)

3.8.5  State that light energy is used to produce ATP, and to split water molecules (photolysis) to form oxygen and hydrogen (Hye Soo)

3.8.6  State that ATP and hydrogen (derived from the photolysis of water) are used to fix carbon dioxide to make organic molecules (Hannah)

8.2.4  Explain the photophosphorylation in terms of chemiosmosis (Kylie)

8.2.1  Draw and label a diagram showing the structure of a chloroplast as seen in electron micrograph (CJ)

8.2.6  Explain the relationship between the structure of the chloroplast and its function. (Matt)

Light-Independent Reactions

8.2.5  Explain the light independent reactions. (Michael)

Analyze Photosynthesis Data

C.4.9  Analyze data relating to photosynthesis (Meena & Eunice)

8.2.8  Explain the concept of limiting factors in photosynthesis, with reference to light intensity, temperature and concentration of carbon dioxide. (Michael)

3.8.8  Outline the effects of temperature, light intensity and carbon dioxide concentration on the rate of photosynthesis (Steve)

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 (David)
