Chlorophyll

Chlorophyll absorbs the light energy required to convert carbon dioxide and water into glucose. It is found within chloroplasts in cells exposed to light.

Chlorophyll is green - so absorbs the red and blue parts of the electromagnetic spectrum and reflects the green part of the spectrum.

Leaves with more chlorophyll are better able to absorb the light required for photosynthesis.
