The pigment in chloroplasts that absorbs light is called chlorophyll
The pigment in chloroplasts that absorbs light is called chlorophyll. Chlorophyll is a green pigment that plays a vital role in the process of photosynthesis. It is responsible for capturing and absorbing light energy from the sun, which is then utilized to drive the chemical reactions that convert carbon dioxide and water into glucose (a source of chemical energy) and oxygen.
Chlorophyll is found in the thylakoid membranes of chloroplasts, which are specialized structures within plant cells. There are several types of chlorophyll, including chlorophyll a and chlorophyll b. Chlorophyll a is the primary pigment involved in photosynthesis and absorbs light most efficiently in the blue and red regions of the electromagnetic spectrum. Chlorophyll b, on the other hand, absorbs light in the blue and red-orange regions.
Apart from chlorophyll, other pigments known as accessory pigments are also found in chloroplasts. These include carotenoids, which are responsible for the orange, red, and yellow colors seen in many plants. Carotenoids absorb light in different regions of the spectrum compared to chlorophyll, thereby widening the range of light wavelengths that can be utilized for photosynthesis.
The ability of chlorophyll and accessory pigments to absorb specific wavelengths of light is crucial for plants to efficiently harness light energy for photosynthesis. This energy is then converted into chemical energy, enabling plants to grow, produce food, and release oxygen as a byproduct.
