The correct answer is b - energy
Chlorophyll is a green pigment that has light absorbing ability. Light from the sun contains energy in the form of photons.
The photons are trapped by chlorophyll and are used to provide power to split water molecules in the leaf in the process of photosynthesis.
Because chlorophyll is a pigment that absorbs light, it is called a photoreceptor. By absorbing light energy, chlorophyll is vital in the photosynthesis and without it, green plants would not be able to get power to run photosynthesis.
