What pigment absorb light energy when phtosyenthis begins?

Answer 1

In photosynthesis, chlorophyll is the primary pigment that absorbs light energy. It primarily absorbs light in the blue (around 430 nm) and red (around 670 nm) wavelengths, while reflecting green light, which is why plants appear green. This absorbed light energy is then used to convert carbon dioxide and water into glucose and oxygen during the photosynthetic process. Other pigments, such as carotenoids, also play a role by absorbing additional light wavelengths and protecting the plant from damage.
