This process, called photosynthesis, is essential to the global carbon cycle and organisms that conduct photosynthesis represent the lowest level in most food chains (Figure 1). Most living things ...

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 ...

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 ...

That is because previous experiments with monochromatic light have shown that plants mainly use light from the visible wavelengths (400 to 700 nm) for photosynthesis, and that light with shorter ...

In particular, they let in light within the blue and red ranges -- the optimal wavelengths for photosynthesis -- but appear to block ultraviolet radiation from penetrating into their shells where it ...

Photosynthesis: Light is crucial for photosynthesis ... Exposure to specific wavelengths of light, typically in the blue or red spectrum, can stimulate the germination process.
