Here may be more than one pigment in a plant. for example, the yellow green "brassica" morph that you will study this week has a
purple coloration on its stems, leaf tips, and other parts. the purple color indicate the presence of the pigment anthocyanin. what does a plant gain from having more than one pigment?
Answer: It enables them to cover more of the visible light spectrum and therefore be able to harvest more light energy.
<span>Pigments can be defined as the molecule that
absorb specific wavelength of light or they are substances produced by living
organisms that obtain color from selective color absorption. Thus, the function of pigment in plant is photosynthesis
and they use green pigment chlorophyll with other pigments such as yellow and red
pigment which are being used to captures much light energy as possible.
However, plant gain from having much more than one pigment because it enables
them </span>to cover more of the
visible light spectrum and therefore be able to harvest more light energy.
The light needed for photosynthetic reactions tends to be more reds and purple wave lengths. The Green wavelength is reflected. Filtering out the green light will stunt the light reactions of the plant.
