The primary pigment in chloroplasts is chlorophyll. This green pigment plays a crucial role in the process of photosynthesis by capturing light energy from the sun.
Chlorophyll mainly absorbs light from the red and blue parts of the spectrum, while it reflects green light, which is why plants appear green to our eyes. The absorption of specific wavelengths of light is vital for photosynthesis, as it allows plants to convert light energy into chemical energy.
In summary, chlorophyll absorbs red and blue light and reflects green light, making it essential for the growth and energy needs of plants.
