Down
- 1. A technique to separate pigments by molecule size
- 2. The phase of photosynthesis that requires electromagnetic energy from green wavelengths
- 3. The process of light splitting a water molecule into 1/2 O2, 2 H+, and 2 electrons
- 4. Another name of the light-independent reaction
- 5. The conversion of inorganic CO@ to organic molecules such as glucose
