What is the role of pigment?
Pigments are chemical compounds which reflect only certain wavelengths of visible light. This makes them appear “colorful”. Flowers, corals, and even animal skin contain pigments which give them their colors. More important than their reflection of light is the ability of pigments to absorb certain wavelengths.
What is pigment system?
Pigment systems are a group of photosynthetic pigments found in the chloroplast of a plant.

What is the definition of pigment in chemistry?

What are two pigment systems?
Photosystems (Two pigment systems) These processes are associated with two groups of photosynthetic pigments called as pigment system I and pigment system II. Wavelength of light shorter than 680 nm affect both the pigments systems while wavelength longer than 680 nm affect only pigment system I.
What pigment means?
Definition of pigment (Entry 1 of 2) 1 : a substance that imparts black or white or a color to other materials especially : a powdered substance that is mixed with a liquid in which it is relatively insoluble and used especially to impart color to coating materials (such as paints) or to inks, plastics, and rubber.
