Why is the primary pigment found in the chloroplast?

Chlorophyll is the primary pigment found in the chloroplast.

Due to the way of Chloroplast and its ability to "make" its own energy is a advantage, but it also needs something called chlorophyll which helps maintain and distribute the sugars and sun energy to the mitochondria. this is important because which out the color green, all of the sunlight would not be absorb because green is a secondary color, but the primary pigmentation for photosynthesis. this is present in all plants and photosynthic organism.
