Chlorophyll is a pigment that plays an important role in photosynthesis. Water provides the electrons and hydrogen ions needed to power the light-dependent and light-independent phases of photosynthesis. Plants use glucose together with nutrients taken from the soil to make new leaves and other plant parts. Chlorophyll can absorb all the wavelengths of light in the visible spectrum except for the green wavelengths. They do this through a process called photosynthesis, which uses a green pigment called chlorophyll. Accessory pigments are pigments that absorb light energy from the sun and transfer the energy to chlorophyll-a molecules during photosynthesis. glucose (a sugar molecule).
