Explanation:

MIT scientists have found a way to induce plants to give off dim light by embedding

specialised nanoparticles into their leaves, a major step towards using plants to illuminate the workspace.

This technology could also be used to provide low- intensity indoor lighting, or to transform trees into self- powered streetlights.
To create the glowing plants, scientists relied on luciferase, the enzyme that gives fireflies their glow. Luciferase acts on a molecule called luciferin, causing it to emit light. Another molecule called co-enzyme A helps the process along by removing a reaction byproduct that can inhibit luciferase activity.
Researchers packaged each of these three components into a different type of nanoparticle carrier.

The nanoparticles, which are all made of materials that the US Food and Drug Administration classifies as “generally regarded as safe,” help each component get to the right part of the plant.
They also prevent the components from reaching concentrations that could be toxic to the plants.
