While it may seem crazy, the idea that millions of years ago the Earth looked purple is gaining traction. Yes, you read that ...

Focusing on two sections of the chlorophyll absorption spectrum, the researchers examined both the low-energy Q region (yellow to red range) and the high-energy B region (blue to green).

For the study, the researchers examined two specific sections of the spectrum in which chlorophyll absorbs light: the low-energy Q region (yellow to red spectral range) and the high-energy B ...

So, instead, the molecule absorbed all other available light. Even though the Sun emits less light in that spectrum, ...

Plants also contain carotenoids (carotene and xanthophyll) which absorb light from other regions of the spectrum, extending the range of wavelengths absorbed and pass the energy on to chlorophyll ...
