Light of two wavelengths is required to activate two photochemical systems. Together they provide the electrons, protons and enery-rich molecules needed to convert carbon dioxide and water into food ...

Figure 1: Over the past twenty years, the field of lithography has seen a dramatic reduction in both the half-pitch feature size and the wavelengths used, but at very different rates. Extreme ...

extending the range of wavelengths absorbed and pass the energy on to chlorophyll for photosynthesis. The different photosynthesis pigments in leaves can be investigated using thin layer ...

Photosynthesis occurs in chloroplasts found within cells. It is the chloroplasts that contain the green pigment chlorophyll which absorbs light. The plant uses this glucose to grow as well as make ...
