Answer: pigments
Step-by-step explanation:
The energy coming from the Sun reaches the Earth in the form of light and is collected by plants, which have molecules (called pigments) capable of absorbing light.
It should be noted that the main pigment plants have is chlorophyll, which absorbs very well blue and red wavelengths of light (in the visible spectrum) but does not absorb green well (that is why plants are generally green).
Therefore:
Plants gather the sun’s energy with light-absorbing molecules called pigments.
