Why Are Plants Green Instead of Black?

The video explores why plants are predominantly green, despite green being a major color emitted by the sun. It discusses the hypothesis that plants might not aim to absorb maximum light but rather light that doesn't fluctuate much, protecting them from sudden energy changes. A study simulated chloroplasts to test this, finding that plants absorb specific wavelengths to balance energy intake. Evolution has fine-tuned plants to absorb optimal wavelengths, making green the ideal color for photosynthesis, with variations like purple in dense canopies.

What did the simulation of chloroplasts reveal about the absorption of different wavelengths of light?

According to the study, why might purple be the optimal color for plants in a dense canopy?
