Chlorophyll is a pigment found in the chloroplasts of cells. During photosynthesis, chlorophyll absorbs light from the sun and turns it into chemical energy the plant can use as food. Chlorophyll has also been used in alternative medicine and has shown to have medicinal benefits.
Why do plants die?
This can be due to hormonal changes in the plant as well as genetic programming. Senescence is the term used to describe biological aging. One of the most distinguishing characteristics of a dying plant is color change. As plant senescence occurs, chloroplasts begin to break down and photosynthesis declines. The declining production of chlorophyll causes the once green plants to turn yellow. This occurs because the green pigment (chlorophyll) degrades and other pigments called carotenoids are revealed.

Where is the light absorbing pigment found?
Since light absorption is needed for photosynthesis to occur, it makes sense we would find the light-absorbing pigment, chlorophyll, inside chloroplasts (the specialized cells in plants responsible for photosynthesis).
How does chlorophyll help plants?
Chlorophyll is vital for photosynthesis, which helps plants get energy from light . Chlorophyll molecules are specifically arranged in and around pigment protein complexes called photosystems, which are embedded in the thylakoid membranes of chloroplasts. In these complexes, chlorophyll serves two primary functions. The energy by resonance energy transfer to a specific chlorophyll pair in the reaction center of the photosystems. Because of function of the vast majority of chlorophyll (up to several hundred per photosystem) is to absorb light and transfer that light chlorophyll’s selectivity regarding the wavelength of light it absorbs, areas of a leaf containing the molecule will appear green. When a leaf was tested using iodine, only the green areas were shown as positive for starch, meaning that photosynthesis will not occur without chlorophyll.
