Why Chlorophyll is Green?
Chlorophyll in the leaves are structurally similar to hemoglobin in the blood. And one most amazing similarity is that the color of both the compounds is due to the metallic ion located in the middle of the complex compound. And like blood transfer oxygen to every cell in the body to utilize it in energy , chlorophyll also act as an important link in transferring sunlight into chemical energy.
The magnesium complex in the chlorophyll is responsible for absorbing red and blue hues of sunlight and reflecting back green light which makes every tree and plant look green. There are some plants which looks red or black this is because chlorophyll has evolved in it to be able to absorb most of the sunlight or on the contrary it failed to evolve so that it can reflect green.
